Fuel Filter: Description and Operation

Fuel Filter Replacement:

PURPOSE
Filter is a high pressure canister type that removes even very small (microscopic) particles from the fuel.

LOCATION
Bracket above right rear axle.

OPERATION
Because of high pressures and large fuel system flow volume, 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, restricting fuel, or collect between the sealing surfaces of injectors, preventing them from shutting off fuel completely.
