I decided I am going to install a new fuel line for my car:

LS1, T76gts, 8 psi boost, 60 lb injectors, racetronics pump/hotwire, Fuel lab boost referenced FPR, fuel rails, patriot stg 3 heads, cam.......

What size feed line (single) should I run? I am going to use the stock line as a return. THANKS!

 

Wow this forum is dead. *chirp-chirp*

 

I would go with a -8 feed line and -6 or stock line for the return.

 

Thats what I have.

Bulkhead in stock tank
#8 feed
#6 to stock feed as return

 

Texum speed sad to stick with the stock lines. He said they have made 700-800whp with one pump using the stock lines and rails.

 

IMHO, I wouldnt chance it..

 

I don't see how they could say this is possible on a f/i car. I could possibly see it on a n2o car, but I don't see 1 pump and stock lines supporting those kind of #'s.

Right now I'm using meth to band-aid my weak fuel system.

 

Wow I have never seen 700-800 on one intank pump. Most are lucky to hit 550rwhp on a boost car. Give me a call I can set you up with a complete kit to run your new lines and regulator.
