Might Be Going FI, But I Have A Question
My understanding is that the LS1's have a returnless fuel system or semi returnless as I have read whatever that means. I will need to install an in line fuel pump as well as injectors which is no problem but will I need to run a return line back to the gas tank with this sort of setup and would a fuel pressure regulator be required also?
I want to compile a list of parts I need outside of what a ProCharger kit includes as well as fuel pump and injectors so any help would be appreciated.
