Turbo fuel line size - Scottie?

Recommended Posts

Going to be running new fuel lines for the car in the next few days, I'd like to have lines (feed and return) that will satisfy a 400hp setup. 1/2" feed too large? I was throwing around 3/8" feed and 5/16" return... I'd just like to do this once, and do it right.

 

What do you V8 guys run? At 14psi boost my engine should be using the equivalent fuel as a 5.6liter 400hp engine...

I am currently running a -8 feed line from the tank to the fuel rail and using the original 240Z 3/8 feed as my return. Based on my latest timeslip, I estimate 450+ at the flywheel and I was running too rich so....

 

Of course, you need a pump that can deliver the volume and pressure and a FPR to regulate the pressure. I made a post a couple of days ago but I will repeat it. I advise you to run a 10-guage wire to the fuel pump. You might have 13+v at the battery but I can guarantee if you use the normal 16-guage wire, the pump will have not have enough voltage with that demand.
