CLEANING THE PUMP:
The following is a step-by-step procedure for cleaning the Holley electric fuel pumps. Do all disassembling on a clean bench.
Read all instructions thoroughly and completely before starting.
1. Remove the pump from the car.
2. Remove the 5 bolts from the bottom of the pump.
3. Holding the pump in position, remove the bottom plate. Remove the upper plate gasket and rotor stop plate. Note the
position of the rotor, rotor vanes, flame arrestor (screen), and relief valve arrangement for re-installation.

4. Remove the flame arrestor (note the position of the screen). Remove the rotor vanes and rotor by inverting the pump. Lay
all pieces on a flat clean surface. See Figure 6.
5. Remove the pressure relief screw. The screw is spring loaded. Remove the spring and relief plunger.
6. Clean the base housing with any good quality carburetor cleaner (spray-type only). Blow the base dry with compressed air.
Clean any loose Teflon tape, etc. from the inlet and outlets.
WARNING! DO NOT IMMERSE THE ENTIRE UNIT IN ANY LIQUID. IMMERSION COULD DAMAGE THE ELECTRICAL
CIRCUITRY, RESULTING IN A PUMP MALFUNCTION. A PUMP MALFUNCTION COULD RESULT IN A FIRE,
WHICH MAY RESULT IN PROPERTY DAMAGES, SERIOUS INJURY, OR DEATH.
7. If the relief plunger is rusty, clean it with emery paper. The plunger must slide freely in the base. Check the plunger,
spring, and o-ringed screw. Check that plunger is free in the slide. See Figures 7 and 8.

8. Clean the rotor vanes with emery paper. The vanes must slide freely in the rotor slot. Check that the vanes move freely.
Replace the rotor stop plate. Install the flame arrestor making sure the screen is behind the screen stop. Replace the
upper plate gasket and upper plate. Fasten with five screws.
9. Replace the pump in the car.
