Attwood 93038LP7 Primer Bulb 3/8 in.

Attwood's Patent-Pending multi-layer primer bulb is designed to provide up to 60% more priming output than leading competitors in extreme conditions, while exceeding new EPA requirements to prevent fuel evaporation. Attwood's exclusive three-layer design ensures high fuel pumping output in hot temperatures (up to 122F) and cold temperatures (down to 18F) 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.
