ENGINE SERVICE AND COMPONENTS

5.5.1

Bleeding the Fuel System

The unit is equipped with a mechanical fuel lift pump, mounted on the engine next to the injection pump. The fuel
system is a closed circuit which will require bleeding if loss of fuel has occurred. To fill and bleed the system, do the
following:
1. Turn bleed valve (Red, see
2. Turn the top of the hand priming pump counter-clockwise to unlock it, and then hand pump the manual
plunger until a positive pressure (resistance) is felt. This will indicate fuel flow.
3. Depress and turn the top of the hand priming pump clockwise to lock in place.
4. Start engine. (Refer to
5. When engine is running properly, turn bleed valve clockwise until fully closed.
5.5.2

Servicing Fuel Pump Internal Filter

The internal fuel filter may become plugged or restricted with foreign particles or wax, which can develop if the
wrong grade of fuel is used or untreated fuel is used in cold weather, contaminating the fuel. If the internal filter is
plugged, the engine will lose power. Therefore, the filter must be cleaned on a regular basis. The quality of the fuel
will affect the filter cleaning schedule (refer to
1. Turn nut counter-clockwise to loosen and remove
2. Remove banjo fitting and let it hang loose.
3. Turn filter counter-clockwise and remove. Check and clean.
4. To install, reverse steps a through c.
