Fuel Pump
The fuel pump, mounted near the blower housing
and the air cleaner cover, allows remote fuel tank
installations on some engines. The pump is
operated by vacuum pulses from the engine.
NOTE: The fuel pump itself is not serviceable. If
the pump does not operate after inspection and
proper installation, replace the pump.
Removal
1. Close the fuel shut-off valve, if equipped.
2. Release clamps and disconnect fuel lines
(A, Figures 1 and 2) and vacuum line (B)
from the fuel pump (C).
3. Disassemble shut-off valve and fuel filter,
if equipped, from hoses and set aside.
4. Remove the two screws that secure the
fuel pump and mounting bracket.
Inspection

• Restrictions or leaks in vacuum or fuel
lines
