FUEL PUMP

REMOVAL

Install a hose pincer (P/N 295 000 076) on fuel supply line close
to pump inlet.

Disconnect fuel outlet line(s).

Disconnect impulse line.

Remove screws securing fuel pump to chassis.

PUMP VERIFICATION

Check fuel pump valves operation as follows:

Connect clean plastic tubing to the inlet nipple and alternately
apply pressure and vacuum with pump of leak test kit. The inlet
valve should re-lease with pressure and hold under vacuum.

Repeat the same procedure at the outlet nipple. This time the
outlet valve should hold with pres-sure and also under vacuum.

Check impulse diaphragm and gasket as follows:

Connect clean plastic tubing to the impulse nipple and plug vent
hole on top cover with a finger. Either applies pressure or
vacuum using the pump (P/N 529 021 800) from the Engine leak
tester kit. The diaphragm/gasket must not leak.
