Fuel Pump: Description and Operation

Fuel Pump And Filter:

PURPOSE
Supplies fuel to the carburetor.

LOCATION
Under the L.H. side of the vehicle, in front of the rear tire.

OPERATION
When the fuel pump coil is energized by intermittent pulses (8 to 12 Hz) generated in a completely sealed electronic circuit. The plunger operates in a reciprocating motion which provides pumping action to discharge fuel. Flow rate of fuel changes as plunger stroke varies with pressure on delivery side, regardless of the number of vibrations of plunger. Therefore, the pump discharges only the required quantity.

CONSTRUCTION
This fuel pump is a non-disassembling, non-contactor type with a solenoid plunger pump.
