3-14. FUEL FILTER, STRAINER, AND FUEL LINES - MAINTENANCE INSTRUCTIONS.
The maintenance instructions contained in this paragraph are as follows:
3-14.1. FUEL FILTER - MAINTENANCE INSTRUCTIONS.
a. A fuel filter (secondary), is used to remove impurities from the fuel. It is installed between the fuel
pump and the fuel inlet manifold in the cylinder head. The replaceable paper-type element can remove
particles as small as 10 microns.
b. The fuel filter operates under pressure. Fuel enters through the inlet passage in the cover and into the
shell surrounding the filter element. Pump pressure causes the fuel to flow through the filter element where dirt
particles are removed. Clean fuel flows to the interior of the filter element, up through the central passage in
the cover, into the outlet passage, and then to the fuel inlet manifold in the cylinder head.
