SERVICE INFORMATION 0B–5
Air Bleeding
When the fuel filters are serviced or the fuel tank emptied,
air enters the fuel system.
The air will block the smooth flow of fuel to the engine. It
must be removed by bleeding the fuel system.
1. Loosen the priming pump cap.
2. Manually operate the priming pump (1) to force fuel
into the injection pump.
3. Use a wrench to loosen the air plug (2) on the fuel filter.
4. Operate the priming pump until there are no bubbles
in the fuel being discharged from the air plug (the fuel
is discharged in a solid stream).
5. Tighten the priming pump cap and the air plug.
Feed pump strainer
1. Remove the joint bolt (feed pump intake side).
2. Remove the strainer by turning it counterclockwise.
3. Clean the strainer.
4. Reinstall the strainer and joint bolt.
5. Bleed the fuel system (refer to the previous item).
Fuel tank draining
1. Remove the drain plug at the bottom of the fuel tank.

drain completely.
