PRIMING FUEL SYSTEM
The mechanical fuel lift pump is mounted on the engine next to the
injection pump. This pump has a manual plunger for priming the fuel
system when the fuel tank has been run dry.

WARNING
Keep clear of rotating belts and pulleys.
To prime the fuel system, use the following steps:
1. Turn the bleed valve (Red) counter-clockwise until fully opened.
2. Turn the top of the manual fuel pump plunger counter-clockwise to
unlock it. S-L-O-W-L-Y (up/down once per second) pump the
manual plunger until positive pressure (resistance) is felt. This may
take up to 200 strokes. Positive pressure indicates fuel flow.
3. Continue to pump S-L-O-W-L-Y (up/down once per second)
approximately 100 more strokes to fill the filter and bleed the air out
of the lines.
4. Start engine. It may be necessary to continue to pump until the
engine starts.
NOTE
Running the engine for an extended period of time with the
manual plunger up can cause a priming pump failure.
5. Depress and turn the top of the manual plunger clockwise to lock in
place.
6. When engine is running smoothly, turn bleed valve clockwise until
fully closed.
