6. Troubleshooting

If you experience issues with your engine's fuel delivery, consider the following troubleshooting steps:

Common Issues and Solutions:

• No Fuel Flow / Engine Not Starting:
  • Check fuel tank level.
  • Inspect fuel lines for kinks, blockages, or damage.
  • Verify fuel filter is not clogged.
  • Ensure all fuel line connections are secure.
• Fuel Leaks:
  • Tighten all fuel line connections.
  • Inspect the fuel pump gasket for proper seating and damage. Replace if necessary.
  • Check fuel lines for cracks or punctures.
• Poor Engine Performance:
  • A failing fuel pump can lead to inconsistent fuel pressure. If other fuel system components are ruled out, the pump may need replacement.
  • Ensure the fuel system is free of air bubbles.
