- Carefully relieve any pressure in the fuel system. Have rags ready to catch any fuel spillage.
- Identify and disconnect the fuel lines from the old priming pump assembly. Note their orientation.
- Remove the mounting hardware securing the old pump and remove it from the engine.
- Install the new priming pump assembly in the same location and orientation.
- Securely reconnect the fuel lines to the new pump.
- Reconnect the negative battery terminal.
- Squeeze the new primer bulb until it feels firm to prime the fuel system.
- Thoroughly inspect all connections for any signs of fuel leaks before attempting to start the engine.
Troubleshooting & FAQ
How do I know if my priming pump needs replacing?
Common signs of a failing priming pump include a bulb that won't get firm when squeezed, visible cracks or fuel leaks on the bulb or lines, or difficulty starting the engine due to fuel starvation.
Is this a direct fit for my specific Mercury engine?
This assembly is designed for Mercury FourStroke outboard models from 2.5 HP to 60 HP that use a primer bulb system. To guarantee a fit, please verify your original part number is 895124 before ordering.
What is the function of a fuel priming pump?
A priming pump is a manual bulb that you squeeze to draw fuel from the gas tank, through the fuel lines, and into the engine's fuel system. This ensures there is adequate fuel available for the engine to start easily.
What causes a primer bulb to fail?
Over time, exposure to fuel and UV light can cause the rubber material to degrade, becoming brittle and prone to cracking. Cold weather can also make the material less flexible and harder to operate.
