- 1 x Installation Instructions
Installation Notes
- Disconnect the battery and relieve fuel system pressure according to the manufacturer's service manual.
- Remove the existing fuel pump assembly from the fuel tank or module.
- Carefully disassemble the assembly to access the high-pressure pump component. Note the orientation of all parts.
- Remove the old high-pressure pump, O-rings, and seals. Clean all surfaces thoroughly.
- Install the new high-pressure pump into the assembly, ensuring all seals and connections are secure.
- Reassemble the fuel pump module and install it back into the boat.
- Crucial Step: Before starting the engine, prime the fuel system. Cycle the ignition key several times (without starting the engine) to allow the pump to pressurize and fill with gasoline. Failure to do so will cause a dry start and void the warranty.
- Once primed, start the engine and check for leaks and proper fuel pressure.
Troubleshooting & FAQ
How do I know if my high-pressure fuel pump is failing?
Common symptoms of a failing high-pressure pump include difficulty starting, engine hesitation or stalling (especially under load), rough idling, decreased top-end power, and poor fuel economy. A fuel pressure test showing lower-than-specified pressure for your engine model is a definitive sign.
Is this the complete fuel pump assembly?
No, this listing is for the high-pressure fuel pump *component* only. It is designed to be installed inside the larger fuel pump assembly (e.g., Volvo Penta 23306461 or 23794966). You must reuse your existing assembly housing.
Does this pump fit carbureted engines?
No, this is a high-pressure pump specifically designed for Electronic Fuel Injected (EFI, GXi, Gi, etc.) engines. It is not compatible with older carbureted models.
What is a "dry start" and why is it bad?
A dry start occurs when the fuel pump is run without being fully submerged in or primed with fuel. The fuel acts as a lubricant and coolant for the internal pump components. Running it dry for even a few seconds can cause immediate and irreversible damage, leading to premature failure. Always prime the system before starting the engine.
What is the recommended replacement interval?
There is no fixed replacement interval for fuel pumps. They are typically replaced only when they fail or show signs of performance degradation. Lifespan is affected by fuel quality, ethanol content, and operating conditions.
Why are the year ranges missing for compatible engines?
Volvo Penta often uses the same components across many years for a given engine model series (e.g., 5.7Gi). Compatibility is determined by the engine model code and the part number of the fuel pump assembly it uses, rather than a specific production year. Always verify the part number on your existing pump or in your service manual.
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.
