GENERAL INFORMATION
The Mallory Fuel 110 Series Electric Fuel Pump is a high volume fuel pump designed for high performance street
and marine applications. The operating fuel pressure is factory set at 7 PSI. Normally, a fuel pressure regulator is
not necessary. We recommend a 5/16" or larger fuel line with this fuel system.
The Mallory Fuel 140 Electric Fuel Pump is a high volume high pressure fuel pump designed for high performance
street, racing and marine applications. The operating fuel pressure is factory set at 12 PSI. This pump must be
used with a fuel pressure regulator to prevent carburetor flooding. We recommend a 3/8" or larger fuel line with
this fuel system.
The Mallory Fuel Series 140 Part Nos. 4142 and 4142A come with a 3 Port Return Style Regulator. These fuel
systems must have a fuel return line installed between the fuel pressure regulator's fuel return port and the fuel
tank. We recommend a 3/8" or larger fuel return line.
When installing the fuel pump fittings, use a thread sealant compound (you can find this at a hardware store) on
the fitting threads. Do not use Teflon tape. Teflon tape can get into the Gerotor and lock the pump. Also, do not
overtighten the fittings. This could damage the fuel chamber.
Be sure to install a suitable fuel filter (minimum 40 micron filtration) between the fuel tank and the fuel pump. The
Mallory COMP FILTER® Series Part No. 3140 is recommended. This prevents debris from becoming wedged in
the fuel pump's Gerotor and locking it.
