Fuel Systems

Fuel Systems

Single-handedly, one of the most important, yet overlooked parts of the LS-swap. Your fuel system is equally important to your drivetrain....right up there in importance with the actual motor and transmission themselves. Face it: no fuel, no movement. And the LS requires a specific fuel pressure requirement. Everything that we sell here is compatible with the LS system's required fuel pressure and LPH. Now it's just a matter of what you are trying to power and how much you need: 400 HP or 4,000 HP.
