so i was wondering if i should just go bigger diameter on my fuel feed line. I plan on running twin 255 pumps into a single -6 line and putting a Y at the rails where a -6 line runs into the rear of each rail. i was going to put a bypass regulator at the front of both rails with the return going back into the stock feed line.

i wasn't sure if -6 feed would be adequate but seeing as how most fuel rails would bottleneck a -8 or above feed down to 3/8th or -6 inner diameter at the rail anyway, i figured -6 would be ok as long as pressure holds in the rail.

the goal is to make 700 rwhp on 93octane with this setup.

im running a stock feed line (3/8's) with twin 255's and stock rails until i can upgrade my entire fuel system. been told by it should be adequate, find out soon. if i was going through the bs of running a new line though i would go at least -8 and do it once

If you havent done it yet just do the -8. The -6 will be fine though. Im running 700rwhp on E85 through a -8 into the stock rail.

100% agree and I'm doing the same except I have Speed Inc rails.
