Drax240z Posted August 18, 2000 Share Posted August 18, 2000 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... ------------------ Drax240z 1973 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted August 19, 2000 Share Posted August 19, 2000 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. ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
