Parts Desk Insights
Best Use Case: Best suited as a replacement primer bulb on larger outboard or inboard/outboard engines that use 1-1/4-inch fuel line. Commonly installed during fuel line overhauls, seasonal recommissioning, or when an engine is hard to prime or loses fuel pressure between uses. Always confirm your fuel line inner diameter before ordering — this bulb is designed specifically for 1-1/4-inch line and is not interchangeable with smaller sizes.
