FUEL PUMP TEST
Operation
The diaphragm is pulled left by the plunger
allowing fuel to be sucked into the fuel chamber.
Fuel is pushed out from the pump until carb
float chamber is filled with fuel, and then the
cut-off switch cuts off the circuit.
When the spring pushes the diaphragm further
to the end, the cut-off switch turns on and the
solenoid coil pulls the plungerwith the diaphragm
forcing fuel into the fuel chamber.
NOTE:
When the main and engine stop switches are ON,
the fuel pump relay is activated for five
seconds atwhich time the fuel pump operates.
