Installation Guide

  1. Safety First: Disconnect the battery terminals to prevent electrical hazards. Work in a well-ventilated area.
  2. Relieve Fuel Pressure: Locate the schrader valve on the fuel rail and carefully depressurize the system. Have a rag ready to catch any fuel spray.
  3. Disconnect Lines: Carefully disconnect the fuel inlet and outlet lines from the fuel pump assembly. Note their orientation.
  4. Disconnect Electrical Connector: Unplug the electrical harness connected to the pump.
  5. Remove Old Pump: Unscrew the mounting bolts holding the fuel pump assembly to the engine block. Remove the old unit.
  6. Install New Pump: Position the new fuel pump assembly and hand-tighten the mounting bolts. Torque them to the manufacturer's specified value.
  7. Reconnect Components: Reattach the fuel lines and the electrical connector securely. Ensure all fittings are tight.
  8. Final Checks: Reconnect the battery. Prime the fuel system by turning the key to the 'On' position a few times. Start the engine and carefully inspect for any fuel leaks around the connections.

Troubleshooting & FAQ

Q: How do I confirm this part fits my specific engine?
A: The best way is to match your engine's serial number to the ranges listed in the "Compatible Engine Models" table. You can also verify by cross-referencing your existing part number with those in our list. When in doubt, use the Mercury Parts Catalog link to see exploded diagrams for your model.

Q: What are the symptoms of a failing fuel pump?
A: Common signs include difficulty starting, engine sputtering or stalling (especially under load), reduced power and acceleration, or a whining noise coming from the fuel pump location.
