Fuel line sizing

Waffles · 07-28-2011, 08:15 AM

So i am working on getting my bridgeport 12a in, and forgot to account for one thing. The factory fuel hard lined(feed and return) are TINY. I am planning on switching to woven pushlock feed, and switching the OE feed line to a return line. With the setup below, what would a good fuel line size be? I am thinking -8 should be fine, but my experience with rotary fuel systems is small.

Setup:
12a bridgeport
RB Holley intake
Holley 650
140 GPH pump

1/2" feed and return line will be more than enough.you can buy a roll of 1/2 aluminum hardline from jegs for about $40.00. enough to do your car....
you cant go too big on your fuel system though , so if you wanna do -8 then go ahead...
