Description
Attwood Primer Bulb 1/4" | Boat Supply Store
This Attwood Primer Bulb is engineered for optimal fuel system priming in demanding marine environments, addressing the critical need for rapid engine startup, especially during cold weather or after extended periods of inactivity. Its exclusive three-layer construction prevents collapse under vacuum and bursting under pressure, maintaining integrity in your outboard or inboard fuel lines. The low-permeation material significantly reduces fuel evaporation, and its high-efficiency check-valves deliver over 60% more output per pump than leading competitors with minimal fuel restriction (<1kPa at 50 L/hr).
