Attwood Primer Bulb - 3/8" Inner Diameter Hose

The Attwood Primer Bulb with 3/8" Inner Diameter Hose is an essential component for boaters and anglers who rely on dependable engine starting in marine environments. This product is particularly useful for those operating small outboards, cabin cruisers, or auxiliary engines, as it helps to eliminate air in the fuel line, a common issue that can prevent engines from firing.

Engineered with flexible and durable elastomer construction, this primer bulb is designed to withstand the challenges of ethanol-blended fuel, UV exposure, and temperature fluctuations. The one-way check valves inside the bulb ensure that fuel flows toward the engine while preventing backflow, maintaining consistent priming pressure with each squeeze. This design is crucial for effective fuel system priming.

Experienced boaters and commercial anglers trust this primer bulb as a reliable replacement or upgrade part. It is compatible with standard 3/8" hose connections, making it easy to install with the necessary hose clamps. Keeping a spare primer bulb on hand is a smart move for anyone who spends time on the water.
