Yes. Doesn't make any sense. Has anybody ever experienced an extremely loud clicking noise from their regulator? What I thought was some kind of drivetrain click, ended up being the regulator.

I can put a long ratchet extension up to it, and sure enough, it sounds like a valve WAY out of adjustment.

It doesn't follow engine rpms. If I move my TPS by hand, the clicking becomes much faster without moving RPM's much. I don't understand what can be making the noise in there. I thought it was just a diaphram.

Should I just swap it out with an adjustible, or is an OEM fine?

hhmm, I have a similar "ticking" sound under the plenum. I thought it was my distributor cap. So after I changed all my ignition components, its still clicked. So I'm guessing we both have the same "click". Sometimes I can hear mine clicking outside of the car... I have not noticed a drop in performance. Let me know if you figured out what it was...

i have the same problem...mine started when i swaped over to a edelbrock back and slp runners...ever since then the clickin has been there. i have posted befor and have been told no big deal dont worry about it so i dont....been over a year and about 3k and no problems

eurostylin

Well, this engine is in a jeep wrangler, and I don't even have inner fenders. The thing is really loud.

I'm going to order up an adjustible regulator, and post up if that fixed the problem.

Whats odd, I drove about 50 miles on a 1/2 tank of fuel. (trail miles) I filled up right after the ticking started, and I only achieved 30 miles on 3/4 of a tank.

I think its letting too much pressure by now, and running super rich. Oh well, I'll have an answer for you shortly.

Whats the best fuel regulator to go with? Or are they all the same

thats funny.. I recently replaced my fuel rail and added a TPIS fuel pressure regulator, and shortly after I can hear a loud drivetrail like ticking noise that I havn't been able to source. I'm going to check my afpr, I'll bet you thats it.

355tpipickup

iTrader: (5)

yea just start the car and touch the fuel rail, injectors, and or the AFPR and you should be able to feel the clickin noise....it sure is loud on mine to, kinda wish i could get it to stop

eurostylin

quick update, replaced FPR and the clicking is all gone.

All nice and quiet now.

Odd - I have a clicking noise as well, and I swear it's an exhaust leak, but I have gone over the bolts and tightened them down so many times. I'll have to see if I feel that vibration...

burnout88

What brand regulator did you go with?

Viprklr

iTrader: (5)

My Holley AFPR has clicked loud from day 1. I don't understand why either but it's kinda hard to hear over all the other noises.

MP81

Does the clicking get faster as RPM increases for you guys?

Viprklr

iTrader: (5)

Nope.

355tpipickup

iTrader: (5)

mine does get a lil faster with pem noise but it wont keep with with the rpms so i know its not a low end knock....i think its just the injectors speedin up! just not sure why it has done it ever since i did the highflow base/runners swap.... never made noise befor, loud anyways

eurostylin

Ok, The clicking is back. Swapped out regulators AGAIN, and its still clicking.

I think it was a fluke it had stopped after I changed the regulator the first time. It is so loud, it drives me nuts. My engine is a beast, and its ashame the nice sound of flowmasters is taken over by this click. I've only driven this thing 20 miles since I first updated this post. With warm Michigan weather approaching, I want to have this thing ready for the trail!.

Now, What is this click from? Is it from the FPR releasing pressure to the return line? I have GREAT fuel pressure on the rails, but this doesn't tell me what my pump is putting out. Wonder if my pump faulted into some crazy high pressure? If I have a ton of line pressure, that would make sense it would make a louder click when it pulses.

Help!

MP81

I dunno what it is, but I get that clicking too, and it is loud, especially under acceleration?

thunder85

iTrader: (1)

this ticking you all got... its louder than the injectors? is it in sync with them?

eurostylin

The ticking increases if I don't hit the gas pedal and just push the tps sensor down slightly. It increases with injector pulse. I'm going to buy an adjustible fuel pump right now and see if I can alter the ticking by increasing/decreasing fuel pressure. I have my pump here on my workbench, and it says 95PSI on it, of course thats way to much...

eurostylin

Ok, update time.

I swapped out my old inline fuel pump for a carter 5000. Two things, HOLY &%#$ and damn.

First the good, My jeep now will pull the front wheels off the ground.

Now the bad, Still a tick from the FPR


I had four-five earwigs on the inlet side of my fuel pump!!! They must have crawled in there when I had it disconnected and hanging off my frame 3 months ago while I was replumbing my fuel lines! It was restricting the flow big time and now I can carry major HP through the RPM range!

Guess my next step is to order an adjustable FPR..

pandin

On the TPI fuel system there is a pulser thing just after the fuel pumps. Maybe this is what it is in there to fix?

just wanted to update, mine was a roller rocker clicking.. readjusted it and the noise is gone.

WhiteIrocZ

iTrader: (3)

I have the same problem. Sounds just like an exhaust leak or a rocker loose. I checked all the rockers while the car was running with oil deflectors on the rockers and its not them. Definitely no exhaust leak with brand new ultra seal header gaskets and ball type flanges. Its driving me crazy.

eurostylin

I know its not an exhaust leak either. I used a 3' socket extension and went all the way around the block on each exhaust port. No noises at all. If I put it on the fuel regulator, I hear it, and thats where its originating from. It gets quieter the further away I move from it, but I can still hear it plain as day on the drivers side fuel rail, all the way towards the front.

83Firebird420

i had a strange click like this. sounded like a reaally loud injector. turned out to be the pcv valve!!!? it was only 5000kms old too. i replaced it and only once in a while it makes the tick for a few seconds.

WhiteIrocZ

iTrader: (3)

I may be hearing a lifter ticking or something. I hope not, but that may be the case. It increases with RPM and can be heard at idle. I have no pcv valve, I have breathers on the valve covers. I am sure its not exhaust related. I am getting ready to do an afpr along with new lifters so that will take care of it I am certain.

AMigs87IROCz

Hey guys,
Well it is always hard to give the right direction on a sound concern. But working at a Chevy dealer and S.D. Concepts(performance shop) there will be a consisitant "ticking" nosie called Injector Pulse....I have heard this condition to get louder with bigger injectors/fuel pressure regulator. It is something I looked into with my TPI....by putting your ears to the rail and injectors you can hear them kinda working in sequence. It is the theory the noise is amlified due to the design of the upper intake(plemun, runners, rails), it is more "open" elemented and the noise cannot be detered by having the injectors buried under the intake and stuff.....I am not sure if it the same noise....but heres my

WhiteIrocZ

iTrader: (3)

What I am talking about is an evident ticking. Hood closed, in the car, going down the road. Its starting to sound like an exhaust leak to me which makes no sense, because I have ball type flanges on the collectors and brand new ultra seal header gaskets. Anybody have any trouble out of Hedman headers before with header leaks at the head??

Check for the number 2 injector not touching the runners....

87IROCZ350TPI

Any updates? I've got that ticking as well. I can feel the ticking when I touch the FPR. Mine DOES correspond to the RPMs, but as eurostylin mentioned, that may be do to the TPS, I haven't checked yet.

Has anyone made any progress on this issue?

Here is the deal, I put a new set of Bosch 3 injectors from South Bay in my TPI engine. I also replaced the fuel pressure regulator with their adjustable regulator with the thinking that mine is 20 some years old and now is time to replace it. After going through the usual problems everyone has with the adjustment screw being too long and hitting the plenum and the inability to adjust it with everything installed all of which necessitated modifications in order to use it, all was well until I started it up.

It rattled something terrible from the regulator. The fuel pressure is good. Ajusting the pressure doesn't change the noise much but somewhat less if lowered way down low. I took it apart and put in the old rubber and spring unit. Started it up and same loud rattling. I replaced the whole regulator with the old one and still the rattling. It is definitely coming from the regulator. It is loud enough that you can hear it with hood closed and 10 feet away. It is at same pace as the injector banks firing. Evidently, because the new injectors close more solidly, the metal disk and seat slap hard enough to make a noise. I called South Bay and they said they have never heard of a regulator making noise.

From this thread I'm sure that there has to be more than just me with this problem. Also, this is in a car without the pulsator thing in the tank, but many people remove them anyway so I don't think that's the answer. Just for comparison, before the injector change the engine would idle with absolutely no noise except the very very light injector ticking. The engine has only 500 miles on it since major overhaul.

I know this thread is old but if anyone has had this problem and solved it, I love to hear how. Right now it's embarrassing to drive the car with it making so much noise.

tpi84stepside

I have the same issue with the same products...it sounds like the injectors and the regulator. You can only hear it with the hood opened. So I guess I can live with it.
I put a bolt in place of the screw that they supply with the regulator. So I can now adjust it with the vehicle running.

Update on the noise problem for others in the future.

I knew it was a resonance problem with the injectors. But I changed everything with no success. I removed the stock FPR and installed a Holley remote AFPR. Same problem. I replaced the intake manifold and fuel rail as I had a spare. Same problem. I thought maybe a lifter problem. Changed lifters. Same problem. I installed a TPIS MiniRam intake and fuel rail. Slight improvement!

On the Miniram, the fuel rail is held on with four screws so it is real easy to change injectors. What I found that made a big change was that I backed off the screws by about 1/8 inch while idling. Instantly the noise almost disappeared. Of course I couldn't leave the screws loose so I put four small Orings under the fuel rail to isolate it and not force the injector down into the manifold so tightly.

The injectors prior to this where very tight in their bores and were hard to turn. Now they where still well seated but loose enough to turn easily. The noise is slightly louder than normal but not heard with hood down.

My conclusion is that it is a combination of things. First, new injectors shut down faster and more solidly than originals. The orings on the injectors being new are stiffer and grip the bore tighter. My setup has no in tank resonator so that the pump pulses are very strong and resonate through the intake much like a echo chamber. Other than that, I don't yet have a complete answer but at least it is drivable without embarrassment.

I have a Miniram and Bosch injectors, you can feel the pulse in the fuel line, it's very loud with my hood open but my car is so loud that with the hood down you cant hear it, anyways I'd like to add that I have had the noise with and now whitout the pulsator.

utilityguy2

iTrader: (1)

Thanks for the input. At least I'm not alone. It is very easy to put small orings or thick sticky back rubber tape under the fuel rail which will lessen the noise significantly. Good Luck.

I just installed Bosch injectors from Southbay, now I have a loud ticking coming from the regulator. Also my 89 5.7 does not have near the power it used to have. I will update from here.

utilityguy2

iTrader: (1)

The Bosh 3 injectors are quite a bit louder than normal but as I found out it is more of a problem that they are squeezed too tightly between the fuel rail and the manifold. Try loosening up the fuel rail bolts about 1/8 inch and you will see what I mean. Of course you can't leave it loose but need to put some type of isolation spacers in there and tighten. The injectors should be fairly easily turned in their bore but not enough to leak.

tpi84stepside

I can easly move all my injectors...I have no pulsator. I'm kinda afraid to loosen anything.
Maybe I'll get some insulation under the hood.

utilityguy2

iTrader: (1)

the injectors can't come out. as long as the orings are seated it's ok just to try and see if it lessens the noise. I don't think the pulsator makes a difference. I've had many people tell me they have one and still have noisy injectors. The one thing about the bosch 3 you get from southbay is that they have the metal extenders that transfer noise more. I returned mine and purchased some Bosch with the pink tops which I believe are ford items from TPIS and they are much quieter but still noisier than my old original stock Bosch ones.

southbay08

The reason why the pink tops are less noisy is because they are an older style injector.
The bosch lll's are known for the ticking noise. As far as the adapter that we apply onto the bottom, it has nothing to do with the ticking.

utilityguy2

iTrader: (1)

Yes I knew that and thanks for responding and working with me on this issue. This level of ticking is not normal and I wish I knew the answer but so far haven't gotten it. The only thing I know for sure is that as soon as I installed the new injectors I had the terrible ticking noise. Even putting the old injectors back in did not solve it (although it was less). I would give anything to go back to the day before I decided to change injectors but that's life I guess. I will let everyone know if the problem is ever solved as it appears that I'm not the only one with the problem.

quisterio

You're not alone...

Ever since I installed my SLP Runners, Edelbrock high-flow base, and tpis AFPR i have had the same ticking noise ever since...

I can't stand it, I can hear it from outside the car, hood up or down, and even inside the car...

I have to do something... The only feasible thing to try would be to loosen up the fuel rail just a touch and see if my injectors are bottoming out against the manifold..

utilityguy2

iTrader: (1)

I just ran mine over to TPIS today and even though they are very good, the only suggestion I got was to live with it and that it is normal clicking. But they agreed that it was a resonance problem that echos within the upper engine. Still no solution. I'm hoping someone stumbles on this and has found a solution. As for yours, I think if you loosen the fuel rail some it will be somewhat better.

I just spoke with the great people at Southbay about another issue. Just to set the record straight, they are a great company and do a great job. I was sorry to learn that they were badly affected by hurricane Sandy. They are just now getting up and running. I strongly endorse their products and customer support.

I've been thinking about this and think that me and you both have the same noise, it maybe Miniram related, for mine I think it's the regulator cause when I use a stethoscope it's loudest there, I was also thinking of just removing it and hooking up a ball valve to test my theory BUT I was also thinking it might be air traped in the line so maybe it's not the regulator, I just need some free time to check it out.

utilityguy2

iTrader: (1)

I thought the same thing after using stethescope. I mounted a holley external regulator and bypassed the original. No change.
I replaced the original TPI intake with the miniram. No change.
Still sounds like it is in the valley under the intake or in the intake.
I replaced lifters. no change.
I have over $2000 and 2 months into this since it started with the noise and still no solution. Only thing I do know is it is caused by the loud lifters echoing in the engine but don't know what to do about it as all lifters are now this noisy from what I gather. And I know that it started after I installed new lifters.

gp90gta

iTrader: (1)

So then maybe we don't have the same noise, mine is coming from the fuel line, if you put your hand on the line you feel the ticking/thumping vibration.

No, probably same as I definitely feel the thumping in the flexible fuel line and fuel rail.

For guys with a Miniram and Bosch III injectors.

So I decided to test something out, here's what I did, I bought a pulsation damper from a Honda (I work from Honda) and an AN fitting, AN t-fitting, banjo bolt and a banjo fitting to mount in line to see if there will be any difference, well there was, so far I put it on the feed side at the fuel line right where the hard line ends and the steel braided hose it (ideally you would want it as close to the rail as posible, but there's not that much room there and this was really just a test), it made a big difference, there's just a small clicking on the feed side but the return side still has about the same ticking, I was going to try it on the return side just to see if it works better that way but it started to rain, I'll get back to it over the weekend and take pic's.

Be warned it wasn't cheap, cost me $100 and that was with the pulsation damper at my price from Honda, I payed $20 for it and I think it was about $38 regular price, but the hardest part to get was the bolt, it's a 12mm x 1.0mm thread by .99" long that I got from a company called pedasus and that alone cost me $21 (with shipping), most regular banjo bolts are 12X1.25 or 12X1.50mm, the T-fitting cost $20 and the coupler was $6, banjo fitting was $22, these came from Jegs with shipping cost me total of $58.
