So I found the diagram with all the russell fittings and fuel filter/regulator. My questions is how do you cut the braided line (20ft right?) and where does it go? My car is an 85 and originally carb'd. I'm trying to find out as soon as possible because summit is having a sale on their Russell products lol. And searching isn't quite answering my ?s. thanks in advance guys.

 

Cut it with a hacksaw if you don't have an electric or pneumatic cut-off wheel.

What do you mean where does it go? Wherever you want it to.

 

Lol. I guess that sounded really dumb...I did give a warning though. I was trying to ask if that's all the fittings that I'd need to plumb the system from the back of the car to the motor. Thanks for the reply btw.

 

Is there a reason you want to plumb the entire car with it?

 

Well I was under the impression from all the reading that since my car is originally carb'd that I have to run all new fuel injection lines cause the original ones won't work for an Lsx swap.

 

Your impression would be correct....assuming you will be running a fuel pump in the tank itself that is high enough for fuel injection(50psi atleast).if your not changing the pump in the tank then you can run a inline fuel pump(inline with the main feed fuel line) and then you also need some type of fuel regulator..preferably adjustable and then make a braided line upto the fuel rail on the lsx.You can place the fuel pump and fuel pressure regulator at any point you want on the car ..you will see most guys who done this..did it under the hood for ease of service and making a short braided line.Most stock lsx car fuel rails are returnless sytems..meaning there isnt a fuel return line to the tank..it will connect to the regulator,then cap off the fuel tank vent line and use a vented gas cap.Hope that helps.the diagram on here that another member posted with all the russell fittings etc are for the guys who already had the fuel injection motors where they use the corvette fuel regulator with a few fittings and then either run braided line upto to the rail or use the stock feed line and cut it off somewhere under the hood with a fitting and make a short braided line to the rail which is what I did,saves from buying 20ft of line when stock line is more than adequate.

 

See how that information would be helpful in the first post?

 

^^^ Lol.Dont be afraid to ask questions even if they sound dumb..but dont get mad if you get equally dumb response next to the answer lol.As you can you..there are options..you dont have to use that diagram or all of that braided line.

 

86 are you saying that I don't necessarily have to buy that amount of braided line? Thanks for explaining this to me.

 

lol yup! if planned right..maybe a few ft of braided line..i think on my setup I used about 8ft total.I cut the main feed line on the frame rail drivers side as close to the motor as i could..then used a fitting there,then made braided line and fitting from there to the fuel rail.I put the corvette regulator where my stock regulator was and cut the feed and return line just before the regulator and made 2 short braided lines to connect the regulator and on the opposite side of the regulator to feed line was another short braided line.This is only because Im already fuel injected pump in the tank.

For you..im not sure if the tank has a return line on carbed cars..its been soo long since my 305 carb came out and I had a donor car and swapped tanks and all the lines over.But the way it would be is this.From the gas tank going upto the motor.get an inline electric fuel pump,place it along the frame rail secure from everything.Cut the feed line and the pump goes where you made this cut.This is your fuel in and out lines now.

[Gas tank]-------feed line input-----[inline pump]-----feedline output-----[aeromotive regulator]-----output line to lsx fuel rail.

if your using all new line or not is upto you and you will need whatever fittings to suit.Return line would look like this.

[Gas tank]-----return line-----[aeromotive regulator]

Dont know if anyone asked But..are you staying fuel injected or going carb on the lsx?if your staying carb setup on the lsx then this is much easier lol.

 

Summit Racing sells a tool to cut braided fuel line, SUM-900040. I'm going to get one for myself, or look at the hardware store for something similar in the plumbing section. I've done the hack saw method before and have no desire to try again.

Braided steel hose covering is very abrasive stuff and will rub through paint, wires, and about anything else it touches. I've had a fire when the braiding rubbed through a wire and then the wire sparked and blew a hole in the fuel line. I'm using braided nylon covered line. The covering just has to be tough enough to resist rocks and debris on the road and is not integral to the strength of the hose.

 

i used a 8" cut off wheel on my chop saw to cut my lines.

if you have carbed lines, you cannot use them as-is, since they do not have fittings on them to take the high pressure of fuel injection. If yours are squeaky clean (not rusty), and you can do double flares on them, you can use them. However, as a few factory carb guy, I found it was better to just do braided from front to back and toss the factory lines.

 

In place of the aeromotive fpr I can put the corvette fuel filter right? And thanks for the heads up on the braided lines. My original lines are not in the best shape lol so I'll be running front to back. I'm trying to do this the simplest way possible.

 

if you're not doing a crazy high horsepower build, just use the corvette filter/reg. feed from tank to filter, return from filter to tank, and feed to engine from filter. keep it simple

pocket's got a couple charts out there, use the basic one; he's got a blower on his setup now, so the return style fuel system is a bit better for fuel pressure control on his thirsty motor

 

Thanks yall

 

Some more questions....I found a fuel sending untit and pump out of an 85 iroc for 150. Is this about right and if not where can I find it? If no one can tell, I'm putting all the parts together for my fuel system and trying to get this right.

 

that's quite a bit for a sending unit and a pump (that you'll have to swap out anyway). i managed to grab my sending unit from one of the members on here locally for about $50. also, make sure you get a fuel injection sending unit; the carb one (yes, some had electric helper pumps on them as i found in my 87) will do you no good in a swap like this

 

I have used a good cold chisel and a 2 lb sledge. Lay the hose on something solid, like a vise, place chisel where you want to cut and whack with hammer. Makes for a easy clean cut in my experience.

I plan to run the hose in place of factory solid line. Just cus the solid lines have some rust on them near filter.

 

I got a 4th gen tank with all the fittings, line and filter for $350 from a local guy on here. To piece it together isnt too much more than that really as I looked into it. He just saved me the time to put it together is all

 

That's what I was thinking. Hope I find one soon. I'm trying to get this done by
Enforce the end of the month.

 

I know this is a little off topic but earlier today at work I was on this message board, this topic to be more specific. My boss came in so I tabbed onto a new web page and started to "look" like I was about to do a google search... he leaned over my shoulder to check what I was doing.... and saw the tab at the top that said...
"Dumb Fu"
He looked at me and asked me what "Dumb Fuc" was..... I obviously had to tab over here to show him I wasnt being naughty at work...... I had to have a little laugh afterwords..

 

There's nothing wrong with the carb'd fuel line for EFI pressure as far as the metal lines go. But, the carb'd V8 lines go over the transmission to the passenger side, while EFI usually connects on the left side of the engine.

I used the factory carb'd V6 metal line from the filter to the engine compartment on the LS1/4L60E swap. Used a Vette filter back where the EFI filter would go. No problems at all.

 

Thanks for the patience guys.

 

It really doesnt matter where the fuel lines pop out in the engine bay for LS1's because the fuel rail can be flipped 180* without issue

The issue with carb lines are the barb fittings arent rated for EFI pressure. Lots and lots of people get away with simply clamping a line on, but it doesnt make it right. Mile_3 has an excellent tutorial of how he converted his carb sender to EFI use by brazing a new fitting on the old line, but the simplest solution is to just find a EFI sender since they're so common

 

Yeah I bought one off of a member and am waiting for it to ship and arrive. And guess what came in today!!!!! Fuel system parts from summit. It really was like Christmas but damn $300+ isn't much in parts lol

 

Should price out my 6.0's fuel system, then see how small the box was

 

I bet that was a grip man lol

 

Where are you guys mounting the vette fpr with braided lines? I got the tank out and now I'm trying to run the lines and I'm assuming I should run them along the frame rail like the original lines. I don't want to mess up the length of lines...hope this makes sense.
