Attwood Primer Bulb Time-Limited

Patent Pending, Attwood’s Primer Bulbs are designed to provide up to 60% more priming output than leading competitors in extreme conditions while exceeding new EPA requirements to prevent fuel evaporation.
The exclusive three-layer design ensures high fuel pumping output in hot temperatures (up to 122°F ) and cold temperatures (down to 18°F) while resisting collapse and hardening. Includes dual high-efficiency check valves that prime in any orientation with low-restriction fuel flow that ensures proper engine operation and aids fuel pump durability.
All Attwood portable fuel components are designed to exceed OEM engine fuel flow requirements.
