Attwood High-Performance Primer Bulb - 3/8" Hose

The Attwood High-Performance Primer Bulb is expertly designed to provide reliable priming for your fuel system while ensuring long-lasting, leak-free performance. With its unique three-layer construction, it prevents collapse under vacuum and resists ballooning or bursting under pressure. Made from low-permeation materials, this bulb minimizes fuel evaporation and delivers an impressive 60% more output per pump compared to leading competitors.

This primer bulb is specifically designed for use with 3/8-inch inner diameter hoses and comes equipped with exclusive high-efficiency check-valves that facilitate faster priming and lower fuel restriction (less than 1 kPa restriction at 50 liters/hour). Engineered hose barbs, combined with stainless steel stepless clamps, guarantee leak-free operation. Additionally, this bulb is compatible with ethanol-blended fuels and exceeds EPA and CARB certification standards.
