Installation Notes
- Disconnect the boat's battery before starting work.
- Safely relieve any pressure in the fuel system according to your service manual.
- Carefully disconnect the electrical connector and fuel lines from the old pump assembly. Note their orientation.
- Unbolt and remove the old fuel pump from the engine block.
- Clean the mounting surface and install the new fuel pump assembly, tightening bolts to the manufacturer's torque specification.
- Reconnect the fuel lines and electrical connector to the new pump.
- Reconnect the battery, prime the fuel system as per the engine manual, and check for leaks before starting the engine.
Troubleshooting & FAQ
How can I confirm this is the right fuel pump for my outboard?
The most reliable method is to match the part number from your old pump to one of the numbers listed in our Part Number Matrix. Additionally, check your engine's serial number against the ranges provided in the Engine & Model Compatibility table.
Is this a high-pressure or low-pressure pump?
This is a low-pressure lift pump. In an EFI system, this pump moves fuel from the tank to the vapor separator tank (VST), where a separate high-pressure pump then sends it to the fuel injectors.
What are the common symptoms of a failing fuel pump?
Signs of a faulty low-pressure fuel pump include difficulty starting, engine stalling at low speeds, bogging down on acceleration, or a complete loss of power. The engine may run rough or fail to start at all.
How often should this fuel pump be replaced?
There is no standard replacement interval for marine fuel pumps. They are typically replaced only when they fail or show signs of performance degradation. Regular use of fuel stabilizer and clean filters can extend its service life.
Can I install this part myself?
While installation is possible for those with mechanical experience and the correct tools, we recommend professional installation. Working with fuel systems carries inherent risks, and improper installation can lead to leaks, poor engine performance, or engine damage.
