Installation Guide

1. Disconnect the battery and fuel lines to ensure safety during installation. Allow the engine to cool completely before beginning work.
2. Locate the existing fuel pump on your outboard engine. It is typically mounted on the side or front of the powerhead.
3. Remove the fuel lines from the old pump, noting their positions (inlet and outlet). Use a container to catch any residual fuel.
4. Unbolt the old fuel pump from the engine block using the appropriate socket or wrench. Keep the mounting bolts if they are in good condition.
5. Remove the old gasket from the mounting surface and clean the area thoroughly to ensure a proper seal.
6. Install the new gasket provided in the package onto the mounting surface, aligning it with the bolt holes.
7. Position the new fuel pump onto the gasket, ensuring proper alignment with the mounting holes and drive mechanism.
8. Secure the pump with the mounting bolts, tightening them evenly in a cross pattern to the manufacturer's torque specifications.
9. Reconnect the fuel lines to the appropriate inlet and outlet ports. Use the provided cable ties to secure lines and prevent chafing.
10. Double-check all connections for tightness and proper routing. Ensure no lines are kinked or pinched.
11. Reconnect the battery and prime the fuel system by squeezing the primer bulb until firm resistance is felt.
12. Start the engine and inspect for leaks around the pump and fuel line connections. Allow the engine to run for several minutes and verify smooth operation.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my Mercury engine?
A: Cross-reference your engine's serial number with the compatibility table above. You can also verify the OEM part number on your existing pump matches 14360A41, 14360A16, 14360A71, or 14360A78. When in doubt, consult your engine's parts diagram or contact our support team with your engine model and serial number.

Q: What are the signs that my fuel pump needs replacement?
A: Common symptoms include difficulty starting the engine, loss of power at high RPM, engine stalling or sputtering under load, fuel starvation at wide-open throttle, and visible fuel leaks around the pump body. A failing pump may also cause the primer bulb to collapse or fail to hold pressure.

Q: How often should I replace my outboard fuel pump?
A: Fuel pumps typically last 3–5 years or 300–500 hours of operation depending on usage conditions and fuel quality. Inspect the pump annually for cracks, leaks, or diaphragm deterioration. Replace immediately if you notice any performance issues or physical damage.

Q: Can I use this pump on DFI (Direct Fuel Injection) models?
A: Yes, this pump is specifically designed for Mercury 75/90/115 HP DFI (1.5L) and 200/225/250/300 HP DTS/DFI 2-stroke models. Verify your engine's serial number falls within the listed ranges before purchasing.

Q: Will this pump work with ethanol-blended fuels?
A: This fuel pump is manufactured with materials compatible with modern ethanol-blended fuels (E10). However, we recommend using fuel stabilizer and draining the fuel system if storing your engine for extended periods to prevent diaphragm degradation.
