frame.
5. Disconnect the fuel gauge connector; then remove
the fuel tank.
CLEANING AND INSPECTING

screen. Account for a seal.
2. Completely drain all contaminated fuel from the fuel
tank; then thoroughly wash the tank out with hot,
soapy water.
3. Dry the tank interior with compressed air.
NOTE: Repeat steps 2 and 3 until all contaminants
are removed.
4. Back-flush the fuel screen with hot, soapy water and
dry with compressed air.
NOTE: If any “pin-holes” are noted in the fuel
screen, replace the fuel level sensor assembly.
5. Inspect the tank cap and filler neck for chipped or
broken threads.
6. Inspect the fuel tank mountings for security, signs of
cracking, or wearing through the tank.
7. Inspect all fuel and vent hoses for cracks, softening,
or deterioration. Replace as required.

Fuel/Vent Hoses
Replace the fuel hoses every two years. Damage from
aging may not always be visible. Do not bend or obstruct
the routing of the vent hose or fuel return hose.
Oil Filter/Oil Pump
NOTE: Whenever internal engine components wear
excessively or break and whenever oil is contami-
nated, the oil pump should be replaced. The oil pump
is not a serviceable component.
! WARNING
Whenever any maintenance or inspection is made on
the fuel system during which there may be fuel leakage,
there should be no welding, smoking, open flames, etc.,
in the area.
