Description
Attwood Primer Bulb 3/8" | Boat Supply Store
This Attwood Primer Bulb is engineered to provide superior fuel system priming for gasoline engines utilizing 3/8" inner diameter fuel hose. Its exclusive three-layer construction guarantees durability by preventing collapse and bursting, while advanced check-valves achieve <1kPa restriction at 50 L/hr for faster priming. This component ensures long-term leak-free performance with engineered hose barbs and stainless steel clamps, maintaining full functionality with ethanol-blended fuels and meeting stringent EPA/CARB standards.
Key Features
- Rapid Priming: Delivers 60% more output per pump compared to leading competitors.
- Durable Construction: Exclusive three-layer design prevents hose collapse and ballooning/bursting.
- Fuel Evaporation Prevention: Utilizes low-permeation material to minimize fuel loss.
- Leak-Free Assurance: Engineered hose barbs and stainless steel stepless clamps ensure a secure seal.
- Low Fuel Restriction: High-efficiency check-valves maintain <1kPa restriction at 50 L/hr for optimal flow.
- Ethanol Fuel Ready: Fully compatible with ethanol-blended gasoline fuels.
- Regulatory Compliance: Meets strict EPA and CARB certification standards.
- Efficient for Small Outboards: Ideal for smaller gasoline outboard engines that require frequent priming.

Common Concerns Answered
Will this primer bulb seal properly on my existing fuel line?
While engineered for a precise fit on 3/8" inner diameter hose, older or non-standard hose materials may present challenges. Ensure your hose barb is clean and that the clamp provides sufficient compression for a leak-free seal. Stainless steel stepless clamps are included for optimal security.
How long will this primer bulb last?
The exclusive three-layer construction and low-permeation materials are designed for longevity. However, premature wear can occur if exposed to excessive UV radiation or harsh chemicals not intended for marine fuel systems. Proper installation and regular inspection are recommended.
Is the price higher than other primer bulbs?
While the initial cost may be higher than basic alternatives, the superior three-layer construction, enhanced priming efficiency (60% more output), and guaranteed leak-free performance with ethanol compatibility justify the investment for reliable, long-term operation in marine environments.
