Troubleshooting & FAQ

How do I know if my fuel pump is failing?

Common symptoms of a faulty fuel pump include the engine bogging down under acceleration, stalling, difficulty starting, rough idling, or surging at consistent speeds. You may also notice fuel leaking from the pump body.

Can this pump replace my VRO pump?

Yes, this mechanical fuel pump is commonly used to replace the VRO (Variable Ratio Oiling) pump when converting an engine to a premix fuel and oil system. This pump does not have an oil inlet and is designed for fuel delivery only.

Does my V6 engine need one or two of these pumps?

Some Johnson/Evinrude V6 models require two fuel pumps for proper fuel delivery. It is critical to check your engine's service manual or inspect the original setup to confirm how many pumps are needed for your specific model before ordering.

What is the 'pulse port' for?

The pulse port connects to the engine crankcase via a hose. It uses the pressure fluctuations within the crankcase to actuate the pump's internal diaphragm, which in turn draws fuel from the tank and sends it to the carburetors.

Is a gasket included?

The original equipment manufacturer (OEM) did not always supply a gasket with the pump, as it was a separate part number. Some aftermarket kits include one, but it is not guaranteed. Always verify the package contents.

What is the difference between an OEM and an aftermarket part?

This listing is an aftermarket replacement (not OEM). It's built to OEM-level specifications with comparable materials and manufactured in an ISO 9002 facility, with batch inspections for consistency.

What are the shipping speed and cost?

We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free, and expedited options will appear at checkout if available for your location.

What is the warranty and return policy?

This part is covered by a 1-year warranty against manufacturing defects under normal use. If any issues arise, please contact our support team with your order details. Returns are accepted within our standard window, provided the item is unused and in its original condition. See our policy page or reach out for instructions.
