GENERAL INFORMATION
The COMP PUMP
®
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 COMP PUMP
®
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 COMP PUMP
®
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 regulators 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 pumps
Gerotor and locking it.
