Re: Need advice: LS ENGINE SWAP

Ast for the flex fuel thing; it also means that your pressure regulator will run a few psi lower than the standard truck FPR. Its worth mentioning so you don't panic if you test fuel psi and it is lower than 58.

Re: Need advice: LS ENGINE SWAP

On a returnless system with a Vette filter/regulator it will be regulated at 58psi. The older retutn type with the vacuum regulator it will be a lower pressure.

If you use a Corvette filter/regulator, then yes it should be at 58psi.
