Installation Notes

  1. Ensure the engine is off and the area is well-ventilated.

  3. Identify a suitable location to cut the fuel line for in-line installation.
  4. Cut the fuel line cleanly with a sharp utility knife or hose cutter.
  5. Check the primer bulb for an arrow indicating the direction of fuel flow. This must point towards the engine.
  6. Attach the fuel line ends to the new primer bulb barbs.
  7. Secure both connections firmly with appropriate hose clamps.
  8. Pump the bulb until it feels firm to ensure it is drawing fuel.
  9. Check for any leaks before starting the engine.

Troubleshooting & FAQ

How do I know if this primer bulb fits my engine?

First, check the Engine & Model Compatibility table on this page. Then, cross-reference your existing part number with our Part Number Matrix. If you are still unsure, compare the specifications and images to your original part before ordering.

What are the signs of a failed primer bulb?

Common signs include visible cracks or weathering on the rubber, fuel leaks, the bulb not becoming firm when pumped, or the bulb remaining collapsed. These symptoms can lead to hard starts, stalling, and poor engine performance.

How often should I replace my fuel primer bulb?

Inspect the primer bulb annually for signs of wear, cracking, or stiffness. We recommend replacement every 2-3 years as part of routing fuel system maintenance, or immediately if you notice any degradation or performance issues.

Is this bulb resistant to ethanol-blended fuels?

Yes, this bulb is constructed with modern, alcohol-resistant rubber compounds designed to handle gasoline containing up to 10% ethanol (E10), which is common in today's marine fuels.
