1-15. GENERATOR FUEL SYSTEM.
Fuel is pumped from fuel tank (1), passes through a primary fuel filter (2) to a mechanical fuel pump (3). From the
fuel pump, fuel is pumped through the secondary fuel filter (4) to the engine. Excess fuel from the engine is returned
to the fuel tank through the return line (5). The primary fuel filter removes large solid particles from the fuel. The
smaller particles are removed by the secondary fuel filter before they can enter the engine fuel injectors.
