3-PORT COMPETITION

FUEL PRESSURE REGULATOR

(RETURN STYLE)

PART NO. 4309

NOTE: DO NOT RUN THIS PUMP WITHOUT FUEL (EXCEPT FOR BRIEF PERIODS WHILE PRIMING).

IMPORTANT: This regulator must use a fuel return line. The fuel return line runs between the fuel return port of the regulator and the fuel

tank. Fuel pressures cannot be adjusted if the fuel return line is absent.

GENERAL INFORMATION

Mallory’s 3-Port, return style regulator regulates fuel pressure between high pressure fuel pumps and carburetors. The

regulator is recommended for Mallory COMP PUMP® 110, and 140 Series Electric Fuel Pumps.

NOTE: This regulator is not recommended for pumps over 200 gallons per hour.

By returning excess fuel and fuel pressure to the fuel tank, this regulator benefits fuel pumps in several ways. The fuel pump will run

cooler, draw less current and will always have full volume output available at the pressure setting. The fuel return line runs between

the fuel return port of the regulator and the top of the fuel tank. The fuel tank must have

provisions for a fuel return line.

This regulator is equipped with a vacuum/boost compensation port (brass barb fitting) that can be used tomomentarily decrease

fuel pressure (vacuum compensation) at idle and part throttle, or increase fuel pressure under blower boost (boost compensation).

While it is not necessary to connect a hose to the vacuum/boost compensation port, it may be

beneficial in some cases. However, the small plug on the barb must be removed before use.
