Parts Desk Insights
Best Use Case: Use this primer bulb when you need a replacement primer bulb assembly for a marine fuel priming line using 3/8" hose/fittings, especially when fuel exposure includes sunlight and/or alcohol-blended fuels.
Common Issues: If hard priming or loss of prime occurs, inspect for cracked/loose hose connections, verify the check-valve side is correct in the installation orientation, and check that the bulb and fittings are seated cleanly on the fuel line.
