Fuel Line Size?

Hello, I am installing an LS1 from a 2000 Z28 Camaro into a pickup truck street rod project and need to know what size supply and return line I need to run. The engine is stock and the fuel cell is in the rear under the bed and has 8AN bungs installed. 8AN is 1/2 inch which seems a little big to me. Thanks for your help, Al.

In general stay at 6 AN or larger. I would run 6 AN supply and 8 AN return in general. Where's the fuel pump? Run 8 AN to pump, 6 AN to engine and 8 AN return.

I'll be putting the pump in the tank, so your saying 6AN from the tank to the fuel rail and 8AN return back to the tank?

Yes that will work.
