MAINTENANCE—PUMP DISASSEMBLY

If your pump fails to produce adequate pressure or

volume, it may require cleaning. Follow the steps below to

disassemble and clean your Mallory Electric Fuel Pump.

Refer to Figure 5 while performing the following steps.
Step 1
Remove the pump from the vehicle and clean pump
exterior. Place the pump on its side on a clean work
surface. Scribe or draw a line across the pump housing,
port plate and fuel chamber so that you can reassemble
the pump correctly.
Step 2
Remove the two fuel chamber screws from the bottom
of the pump. Remove the fuel chamber and port plate.

NOTE: Do not drop the Gerotor from the pump cavity.
Step 3
Separate the port plate from the fuel chamber.

NOTE: Do not drop the air bleed check ball and spring

from the fuel chamber.
Step 4
Place your hand beneath the Gerotor and hold the pump
in an upright position. The gerotor should slide out of the
pump and into your hand. NOTE: Observe the position

of the Gerotor and be careful not to reverse it when

you reassemble the pump. Inspect the gerotor housing
and port plate for wear. If the gerotor has worn through
the plating, return pump to Mallory for repair.
Step 5
Inspect the O-ring and gasket. Replace them if necessary.
Reinstall the air bleed spring and check ball in the fuel
chamber. Place the gasket and port plate on the fuel
chamber. Install the fuel chamber assembly on the pump
housing. Torque the fuel chamber screws.

NOTE: DO NOT OPERATE THE PUMP WITHOUT

FUEL. (Except for brief periods while priming).

IMPORTANT: Turn fuel chamber screws by hand

until they contact the chamber. Then torque to

24 inch/pounds
