Electric Fuel Pump
DESCRIPTION AND OPERATION
Fuel Tank and Fuel Tank Filler Pipe
Fuel tanks (9002) are designed and fabricated of either non-corrosive metal or polyethylene molded plastic.
The fuel tank stores fuel for engine usage. Each fuel tank is of one-piece construction, either welded or
molded design.
Fuel filling is accomplished through a fuel tank filler pipe (9034) attached to the fuel tank and/or external vent
lines within the fuel tank filler pipe and fuel tank.
A venting system is used to provide an air space within the fuel tank when the fuel tank is filled to capacity.
This air space provides for thermal expansion of the fuel as well as being an aid to the in-tank vapor vent
system.
