(1) Fuel priming switch
The fuel system can be primed from the keyswitch or from a remote mounted switch (1).
Turn the fuel priming switch (1) to the ON position. Hold the fuel priming switch in the ON position for 2 minutes.
Verify that the water separator is full of fuel.
If the water separator is not full of fuel, turn the fuel priming switch OFF and then turn the engine start switch ON. This action will cycle the fuel priming pump again.
When the water separator is full of fuel, attempt to start the engine. If the engine starts and the engine runs rough or the engine misfires, operate at low idle until the engine is running smoothly. If the engine cannot be started, or if the engine continues to misfire or smoke, repeat Step 1. The fuel system can also be primed by using the key switch. Turn the key to the ON position for 2 minutes. After 2 minutes the fuel system should be primed. If necessary, by cycling the key switch the system will prime again for 2 minutes.
