How much fuel pressure is required? I have a 1998 LS1 out of a firebird and I'm putting it in a 34 Ford kit car. I need to purchase a fuel pump, but I'm not familar with the amount of pressure and volume requried to run the LS1. Because I'm ignorant to LS1 engines, does it require a return fuel line? Can anyone help? Thanks ahead of time.
