- Remove the fuel tank, if not already removed. Remove the fuel sender assembly from fuel tank. Inspect the fuel pump inlet for dirt and debris. If dirt and debris are found, the fuel pump needs to be replaced.
- Flush the fuel tank with hot water. Pour the water out of the fuel sender assembly opening in the fuel tank. Rock the fuel tank in order to be sure that the removal of the water from the fuel tank is complete. Allow tank to dry completely before reassembly.
- Disconnect fuel pipes at engine compartment fuel pipes. See FUEL LINE DISCONNECT FITTINGS . Clean the fuel pipes by applying air pressure in the opposite direction of the fuel flow. Connect the fuel pipes to the engine compartment fuel pipes.
- Replace the fuel filter. See FUEL FILTER . Install the fuel sender assembly. Install the fuel tank.
NOTE:
Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages. When ever the fuel tank is cleaned, the fuel pump fuel strainer must be inspected. If the fuel pump fuel strainer is contaminated, the fuel pump fuel strainer must be replaced and the fuel pump must be inspected.
NOTE:
When flushing the fuel tank, the fuel and water mixture needs to be treated as a hazardous material. The material needs to be handled in accordance with all local, state and federal laws and regulations.
NOTE:
Only use oil-free compressed air in order to blow out fuel pipes.
