Good To Know

Q: Why is a fuel pressure bypass regulator necessary? A: It allows excess fuel from high-flow pumps to return to the tank, keeping fuel rail pressure stabilized at your target level.

Q: Will this fit car intake manifolds like the LS1 or LS6? A: This specific bypass assembly is designed to clear the taller configurations found on truck intake manifold fuel rails.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
