Product Information

A bolt-in kit that replaces the factory fuel filter and fuel pressure regulator under the car with a high-flow filter and an adjustable multi-port regulator, using the factory fuel lines. Fuel pressure is set by hand with a knob that clicks in steps of about 1 psi, with no jam nut or set screw to fight. The vacuum reference port swivels 360 degrees and takes any of the four supplied fittings, or the plug when a constant fuel pressure is wanted.

Is it normal for fuel pressure to drop quickly after the engine is shut off?

  • Yes. High-flow aftermarket regulators use larger internal parts that do not seal perfectly once flow stops, and pressure comes back as soon as the pump runs again. Long cranking or slow pressure build points to fuel draining back in the pump module, not to the regulator.
