Fuel Pump ?

[Kim57]

I'm putting a LS2 in my project.
What is the best external fuel pump and filter to use?
Do I need to do anything special as there is no return line from the engine back to the tank?
This is all new to me and I don't want to screw it up.

Run an external 255lph Walbro pump and get a filter/regulator for a 99-04 Corvette.

The corvette filter/regulator has a return line built in. So you will have to run return line back to the tank. But the walboro and vette filter works good as stated above.

I am about to cross this bridge as well. What filter do you guys recommend
if you have a return style fuel rail ? Also are you running a filter before the pump or just after?

Thanks.

Hey that resembles my setup! My Vette/Wix filter/reg is on the inside tho. I like your fuel pump brackets better...had to make mine from scratch and that's all I had. Guess I could trim it tho.

Is that a second filter that's on your frame?

there's a big Trick Flow aluminum canister pre-filter, then the Walbro pump, then and a Vette filter/regulator with a return line. Just filtering before the pump to keep it clean and the filter/regulator setup takes care of the fuel pressure and provides the return path...and post-filter capability. overkill????

Correct, about the easiest way to regulate fuel pressure with an LSx swap. That is unless you have a 5.3 where the fuel is regulated on the fuel rail.

If it's an aftermarket billet rail, run the vette filter and cap off one end of your fuel rail. If it is a stock rail, run the return line back to the tank.

Hey Guys,

I am haven't been able to confirm the correct fitting needed for the out flow to the motor side of the filter. I had thought it was a 3/8" outlet. Is this it by chance?

Are the external pumps known to last long?

too broad of a question. Short answer is yes, they work fine and if setup correctly there should be no issues with them lasting.

my whalbro pump is at the back of the cab...should I move it closer to the tank??...I've heard of these pumps being better "pushers" than "pullers"?....

[68GMCCustom]

external pump should be as close to the tank as possible....yes better pushers.

If you use any quick connect fittings, make sure you get the newer ones that have the C-clip instead of the plastic retainer, the ones with the plastic retainer have been known to come off under preasure. Heres the link to a post I did about the fittings http://67-72chevytrucks.com/vboard/s...d.php?t=502781
