4. Fuel Pump
Inspecting the fuel pump
The engine is equipped with one of the following three
types of fuel pump depending on the engine
specifications.
(1) Plunger-type fuel pump
There are two types; one is the standard with a
filter element and the other, compact-size,
without a filter element. As for standard type,
remove the cover and clean or replace the filter
element. On either pump, ensure that the pump
operates normally without fuel leakage.
(2) Diaphragm-type fuel pump
Never attempt to disassemble this type of fuel
pump. Like the compact-size plunger fuel pump,
ensure that the pump operates normally without
fuel leakage.
