INSTRUCTION SHEET
Part Number 5044 Fuel Pressure Regulator for Carburetors (7-15 PSI)
With Idle Bleed and Boost Reference

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 carburetor.

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 carburetor. You may use just one or both of these ports.

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

The #70 jet in the idle bleed will reduce idle pressure by 2-4 pounds. The Race Pumps regulator is much smoother than other designs, so the idle pressure does not need to be reduce as much to allow the engine to idle smooth. Most methanol carburetors will idle good at 8 PSI with the Race Pumps regulator. Installing a larger jet is not recommended.

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 1500 RPMs with the boost reference disconnected. Most carburetors work well with 7 PSI on gasoline and 9 PSI on methanol.
