Maintenance

Contamination is the most common cause of fuel system problems. To ensure best operating results, the fuel must be clean and fuel tanks free of contaminants. Change the fuel filter/water separator regularly and inspect/clean the electric fuel pump filter.

Whenever the fuel system is opened, take the following precautions to prevent dirt from entering the system:

• Cap all fuel lines.

• Work in a relatively clean area whenever possible.

• Complete the work in the shortest possible time.

The following procedures can be accomplished under field conditions:

• Bleeding air from the fuel system.

• Fuel tank and filter system maintenance.

• Electric fuel pump replacement or repair.

• High pressure fuel pump replacement or repair.

• Injection line replacement.

• Common (high pressure fuel) rail replacement.

• Electronic injection nozzles replacement.
