You can't really go "too big" with fuel lines (makes it easier on the pumps to move the volume) but anything bigger than this is a bit overkill for our engines.

Not to be a dick man but there is plenty of research to be done to know what you gotta do to get there. Just a lil info for ya im running a 2.2, Stage 3 Crowers, on 80s and E70 and made 660 rwhp and rwtq. Ran outta fuel at 5100 with twin GTs and a modified hat with upgraded line to the rail. Gonna be doing the LP return style kit. To be on the safe side when running E make sure you have a good 35% more fuel then it would take on pump/91.

8 feed, 6 return would be fine for that setup.

As they said 10an feed and 8am return. Hard to say what length bc everyone will run theirs different. I ran my feed/return up the driver side, feed the back of the rails, mounted the regulator on the EGR block off and ran passenger rail back behind the blower as the driver i used 60deg fitting to regulator.
