Default LS3/427 fuel line size

I have a LS3/427 FI going in my project. I am thinking it will need a
-8 line, thoughts? Also is it the C5's that have the integrated fuel filter and regulator? Thanks

depends on your hp goal and how much fuel is needed. 8AN should be good. c6 has filter,regulator assembly in the pump in the tnk nothing external.


what pump are you planning on using? some kind of replacement like aeromotive eliminator? i really like the secondary systems tha work in conjuction with your factory pump like A&A corvette offers.

my buddys car has a stock factory Z06 in tank pump and the A&A dual pump kit with a F1X procharger it makes 1109rwhp on 93 and 1224 on race gas. the secondary pumps utilize hobbs switch so they only come on and desired boost level.

Your link says it's a carb motor, no fuel injection. You'll have to run a different tank and pump than what's on a C6 (or C5). Your carbs won't work with the pressure from a C6 pump designed for an injected motor.

You might want to clarify that FI for Hal, since it could be interpreted as Forced Induction, Fuel Injection, or even Foreign Import.

I went by the first page post of his supplied link where he stated he was building a carburated engine and "assumed" FI meant boosted. I didn't read any more of the multiple page thread to see when he changed his mind about using carburetors.
