Fuel Filter: Description and Operation

Fuel Filter:

The fuel filter, located next to the engine in the right front of the engine compartment, is a high pressure canister type fuel filter. The filter removes even very small (microscopic) particles from the fuel. Because of the high pressures and large volume of flow in the fuel system, tiny particles can erode away the sealing surfaces of fuel injectors and pressure regulators, causing injector leaks and fuel pressure loss. Larger particles can plug up the tiny orifices in injectors and restrict fuel, or collect between the sealing surfaces of injectors, preventing them from shutting off fuel completely.
