Troubleshooting & FAQ

How do I confirm this pump fits my specific engine model?

The most reliable method is to cross-reference the part number stamped on your original pump with the numbers listed in our Part Number Matrix. Additionally, check your engine model, year, and serial number against our compatibility tables. When in doubt, consult your engine's service manual or contact a professional mechanic.

What are the common symptoms of a failing DFI fuel pump?

Signs of a faulty boost pump include difficulty starting, engine hesitation or sputtering (especially at high speeds), a noticeable loss of power, increased fuel consumption, or a constant whining sound coming from the pump.

Is this a high-pressure or low-pressure fuel pump?

This is an electric boost (or lift) pump. In a DFI system, it works as a low-to-medium pressure pump that supplies fuel from the tank to the high-pressure pump, which in turn feeds the injectors.

Does this kit include a new filter, wiring, or mounting hardware?

This product listing is for the fuel pump assembly as pictured. It does not typically include separate filters, wiring harnesses, or mounting bolts unless specified. You may need to reuse your existing hardware.

What is the 'PH Initialized' attribute?

This is a technical marker from the source data, likely indicating a production or quality control status (e.g., 'Pump Housing' initialized). It does not relate to user-facing functionality or installation.

How can I extend the life of my new fuel pump?

To maximize the lifespan of your fuel pump, regularly replace your boat's fuel filters as recommended by the manufacturer. Avoid running the fuel tank completely empty, as this can cause the pump to overheat and ingest sediment. Using a fuel stabilizer during off-seasons also helps maintain fuel quality.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
