FUEL FILTER COMPONENTS
AND FUNCTIONS
The fuel filter is installed between the fuel feed
pump and fuel injection pump, and removes
dirt and foreign matter from the fuel pumped from
the fuel tank.
The filter element must be changed periodically.
The fuel goes around the filter element. The fuel is
fed through the pores in the filter and discharged
from the center of the cover. Dirt and foreign matter
in the fuel are deposited in the filter element.
