for Part Number 5054 Fuel Pressure Regulator for EFI (45-75 PSI)
with Boost Reference and Idle Bleed

Lightweight Ceramic Valve, Hard Anodized Billet

250" Orifice For Smoother Fuel Pressure at Lower Demand

The Race Pumps fuel pressure regulator installs between the fuel pump and the fuel rails.

The lower port is -8 AN O-ring, this is the inlet from the fuel pump.

The side ports are -8 AN O-ring, these are outlet ports to the fuel rails. You may use just one or both of these ports.

The -4 idle bleed must be returned to the fuel cell.

The #40 jet in the idle bleed will reduce idle fuel pressure by 10-20 PSI.

The -3 port for the boost reference is also the pressure adjuster. Screwing it in increases fuel pressure, out decreases fuel pressure. Set the fuel pressure at 4,000 RPMs with the boost reference disconnected.
