Holley Fuel Regulator Issues

Seems like i cant catch a break with the new parts ive been purchasing. 1st i had a new fuel sending unit go bad after 2 weeks. Now my Holley regulator is not working. Both parts were installed back in March so both are out of warranty. I had the regulator set at 5.5 psi and car was idling awesome. Finally got around to installing my lock up kit for the 700r4 yesterday and car wouldnt start. Had a bad smell of gas and found that the carb was flooding. Well it turns out the regulator was not regulating the fuel anymore. The car has never seen the road and was probably only started 10 times and let idle for 10 minutes each time. So i took off the regulator this morning and opened it up thinking the diaphram must be torn, but it wasnt. Looks to be in really good shape. Could the regulator have gotten stuck? Tried adjusting while on car but no change at all. Has anyone experienced this type of issue with holley regulators? What could have caused this?

Re: Holley Fuel Regulator Issues

Have you checked the pressure between the reg and the carb? Maybe the reg is working...and the needles and seats are not?

That isn't what he asked.

Is the line clear? You have blown through it or otherwise PHYSICALLY VERIFIED that it is CURRENTLY free of obstruction WHILE IT'S IN THE ACT OF SCREWING UP?

I have the gauge between the regulator and carb. When car was working properly it was set at a steady 5.5 psi. The gauge has a maxium of 15psi. When the car was flooding it would shoot past the maximum psi.

Yes, everything is new and tank is clean. See that word in bold letters, YES. Yes means i did blow the line out. So i did answer his question and i added that everything else is new and cleaned out so there wont be any confusion for the people who dont like to read. If you gonna repost what i typed please post my whole sentence.

Yes, I have.
Probably caused by the child slave labor at factory in China.

That's not what you've been asked.

What you've been asked is,

Is the return line clear?

Your response is NOT the answer to that question. To SOME OTHER question maybe; butt not THAT one.

That just sucks cause i aint a rich guy and you spend good money on a product that aint worth a damn. Only one ive been seeing that everyone pretty much loves is the aeromotive brand. Cant see myself spending 200 plus on a regulator. I guess like that old saying goes, if you want to play you have to pay.

Re: Holley Fuel Regulator Issues

Of course I did.ed

Didn't answer the question Vader asked:

HAVE YOU ACTUALLY PHYSICALLY REALLY TRULY ACTUALLY checked to see if your return line is blocked?

Don't tell us about "new"", "pressure " this that or the other. You haven't answered the question yet.

IS YOUR RETURN LINE CLEAR?

Couch potato may have missed this reply. I think we can move on from "is your return line clear". Unless someone wants you to physically crawl through the line and inspect the interior...

Re: Holley Fuel Regulator Issues

I agree.^^

I have, in the past, bypassed the "china parts/reliability" issue, as well as the $$$ fancy parts issue by repurposing OEM parts. In a case very similar to this one, I used a TBI FPR/housing. I chopped off the injector "covers"/hold-downs, pipe thread tapped all three ports (in/out/return), reduced the spring pressure to get it down to 5-7 PSI from the 12ish it was factory set to.....and installed it in a convenient place under the hood. Worked flawlessly for years until and beyond when the vehicle was sold. So that's an option.

There are also returnless cheapy regulators (from Holley and others)....I doubt they'd be any more reliable than the one you bought....but at least they're so cheap you can not care too much and carry a spare.

I dont know brother, but you seem to have a love/hate relationship with a certain word (YES) cause you keep leaving it out when you are quoting me. So i dont see a more perfect time for me to bust out the KISS method then now on replying to your question with one single word, Y-E-S spells YES!!!!

Hey that actually sounds like a really good idea. I have a few tbi housings in my garage. I know you said you no longer have the vehicle but do you have any old pictures on how it was mounted and how it looked?

Sorry, I don't. I actually went to the forums that I posted that build on (it was a Wrangler w/a carb'd 350), and any/all pics were Photophucket'ed. (gone). Sorry.

Went out to the garage and took a look at the tbi regulator. I see where you would tap the in and out ports, but where would you drill and tap for the return line?

Re: Holley Fuel Regulator Issues


Blue arrow is the IN/pressure side, black arrow is the out/return side....no pressure.

"T" into the pressure line at any point between the pump and the regulator, and you got your set pressure, for the carb.
