Fuel Filter: Description and Operation

Fuel Filter System:

PURPOSE
The fuel filters remove foreign material which could damage the injection pump or clog the injector nozzles.


OPERATION

- A primary filter is located on the front of the dash on C+K models. The primary filter also has water draining provisions.
- A secondary in line filter is the final filter before fuel enter the injection pump.
