GENERAL INFORMATION

Mallory’s 4305M regulator regulates fuel pressure

between high pressure fuel pumps and fuel injection sys-

tems. The regulator is recommended for Mallory COMP

PUMP® 60FI, 110FI, or any fuel injection pump designed

to produce 30-100 PSI.

The 4305M regulator is a return style fuel pressure regu-

lator. The excess fuel and fuel pressure is sent back to the

fuel tank through the fuel return line. The fuel return line

runs between the fuel bypass port of the regulator and

the top of the fuel tank. The fuel tank must have provi-

sions for a fuel return line.

This regulator is equipped with a vacuum/boost

compensation port (brass barb fitting) that can be

used to momentarily decrease fuel pressure (vacuum

compensation) at idle and part throttle, or increase

fuel pressure under blower boost (boost compensa-

tion). While it is not necessary to connect a hose to

the vacuum/boost compensation port, it may be ben-

eficial in some cases. However, the small plug

on the barb must be removed before use.

You can mount the 4305M regulator at any angle.

For maximum efficiency, mount it as close as

possible to the fuel injection system. DO NOT

mount the regulator on or near exhaust manifolds.

A bracket is provided for convenient mounting.
