Section VI. FUEL SYSTEM
70. Description
The fuel system consists of a 42-gallon fuel tank, a single downdraft carburetor, a fuel pump, a double air filter to
protect the intake from grit and dirt and a variable speed governor. Included are the necessary fuel lines from tank to
pump and from pump to carburetor and the governor-to-carburetor connections. Figure 18 illustrates the fuel system
schematically.
71. Cleaning Fuel Lines
a. Close the shutoff valve below the fuel tank, and disconnect the fuel line from the tube elbow below the tank (fig.
b. Hold a suitable receptacle below the fuel pump and disconnect the tank-to-pump fuel line and pump-to-carburetor
fuel line from the tube elbows in the pump.
c. Disconnect the fuel line from the carburetor inlet opening, meanwhile holding a shallow receptacle under the
carburetor to catch whatever fuel is in the carburetor bowl.
d. Blow out the fuel lines with compressed air. Make certain that the fuel line connector threads are not stripped or
otherwise damaged.
e. Reconnect the pump-to-carburetor and pump-to-tank fuel lines, and open the shutoff valve below the fuel tank.
f. Operate the fuel pump primer lever a few times to bring fuel up into the pump bowl.
72. Draining and Cleaning the Fuel Tank
a. Remove the drain plug from the bottom of the fuel tank and drain the fuel into clean receptacles for later possible
re-use. It is advisable to filter the gasoline through layers of cheese cloth to remove foreign particles or sediment that may
be present in the tank.
b. Flush the interior of the tank with gasoline, filtering the gasoline into a receptacle as it emerges from the drain
opening. Repeat this process until the filtering cloth indicates that the draining gasoline is free of sediment.
