Locate the primary fuel filter (2). The fuel filters are located on the left side of the engine compartment underneath the hood.
Illustration 3 g01159085
Locate the fuel priming pump switch (3). The fuel priming pump switch is a component of the primary fuel filter assembly. The pump is used when the following operations occur:
Changing the fuel filters
Priming the fuel system
Changing the fuel lines
Purging air from the fuel systemNote: The engine start switch must be in the OFF position in order to prime the fuel system. Do not attempt to start the engine until the fuel system is purged of air.Note: Use a suitable 4 L (1 US gal) container in order to capture the fuel that will pass through the purge valve.
Open the purge valve (4) by turning the valve counterclockwise. Do not remove the valve. Hold the drain hose to the container in order to catch the fuel.
Push the switch upward to the ON position in order to pump the fuel. Note: If the pump will not pump fuel, the pump may be faulty or an air leak may exist on the suction side of the fuel system.
Continue to prime the fuel system until the flow of fuel is free of air bubbles. Fuel should flow continuously from the drain hose.
After air has been purged from the fuel system, close the purge valve.
Push the switch upward to the ON position for approximately 30 seconds in order to pressurize the fuel system. Continue to pump until the fuel filters are full. When the system is pressurized and the fuel filters become full, move the switch downward to the OFF position.
Start the engine. If the engine will not start, further priming is necessary. If the engine starts but the engine continues to misfire, further priming is necessary. If the engine starts but the engine continues to emit smoke, further priming is necessary.
If the engine starts but the engine runs rough, continue to run the engine at low idle until the engine runs smoothly.
Inspect the components for fuel leaks. If fuel leaks are found, identify the source of the leaks and make repairs.
When you have completed the procedures, retrieve the containers. Clean up any spilled fluid. Dispose of the fluids according to local regulations. Dispose of the cleaning materials according to local regulations. Proper care is your responsibility.
