OPERATION
Fuel enters the filter at inlet (C), then flows through filter
element (D) and exits through outlet (B) to the fuel
injection pump. The filter element is housed in a sediment
bowl attached to the base with a threaded retaining ring.
Since water and contaminants settle at the bottom of the
sediment bowl, a drain plug (E) is provided.
Air in the system can be expelled through the air vent
when bleed screw (A) is loosened. Optional priming pump
(F) draws fuel from the fuel tank to fill the filter bowl when
the filter element is changed. The priming pump also
supplies fuel from the filter to the injection pump.
