Fuel System - Inspect
A fault with the components that send fuel to the engine can cause low fuel pressure. This can decrease engine performance.
- Check the fuel level in the fuel tank. Ensure that the vent in the fuel cap is not filled with dirt.
- Check all fuel lines for fuel leakage. The fuel lines must be free from restrictions and faulty bends. Verify that the fuel return line is not collapsed.
- Inspect the fuel filter for excess contamination. If necessary, install a new fuel filter. Determine the source of the contamination. Make the necessary repairs.
- Service the primary fuel filter (if equipped).
- Remove any air that may be in the fuel system. Refer to Systems Operation, Testing and Adjusting, "Fuel System - Prime".
