Fuel Stop Solenoid Replacement
1. Disconnect the 20 wire from the reset switch
to prevent the reset switch from tripping.
2. Disconnect the fuel stop solenoid wire
connector and remove the old fuel solenoid.
3. Connect the fuel stop solenoid wire connector
to the new fuel solenoid.
4. Turn the unit on to energize the fuel stop
solenoid.

energized when it is being installed. If it is
not, the plunger and the linkage may not line

fuel injection pump. Make sure that the o-ring
is positioned correctly during installation to
avoid damage and leaks.
