DIESEL FUEL SYSTEM MAINTENANCE

LEARNING OBJECTIVE: Describe the basic maintenance required for a diesel fuel system.

If all diesel engines had nearly identical fuel system trouble, diagnosis and maintenance procedures could follow a general pattern. But, with the exception of similar fuel tanks and basic piping system, diesel fuel systems differ considerably. Consequently, each engine manufacturer recommends different specific maintenance procedures. However, the tune-up and maintenance procedures described are representative of the job you will do. For all jobs, refer to the manufacturer’s service manual for the fuel system you are servicing, even if you fully understand all procedures.
