This Atwood Primer Bulb is engineered and constructed to deliver the most reliable priming and long-term leak-free performance. The exclusive three-layer construction prevents collapse under vacuum and prevents ballooning or bursting under pressure. The low-permeation material prevents fuel evaporation, and this bulb delivers 60 percent more output per pump than leading competitors.
Features:
It is intended for use with a 3/8-inch interior diameter hose
Exclusive high-efficiency check-valves deliver faster priming and low fuel restriction (less than 1kPa restriction at 50 liters/hour)
