Fuel Filter: Description and Operation

Fuel Filter:

Fuel Filter (High Pressure):

The fuel filter, located near the fuel distributor, 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 and damage the fuel distributor and injectors. Larger particles can plug up the tiny orifices and restrict fuel, or collect between the sealing surfaces of injectors or regulating valves, preventing them from operating properly.

Fuel Distributor Inlet Banjo Bolt Mini-Filter:

A small filter screen (mini-filter) is also built into the banjo bolt at the fuel inlet to the fuel distributor.
