Marine Primer Bulb – Manual Fuel Line Pump

Get your engine firing quickly and reliably with this essential marine primer bulb—an in-line manual pump fitted with dual check valves. Ideal for priming the fuel lift pump and carburetor on outboards and small inboard engines, it lets you draw fuel efficiently without mouth suction, enhancing safety and convenience 

Easy to install inline with your fuel hose, this bulb is compatible with standard 1/4", 5/16″ – 3/8″ fuel lines. By squeezing the bulb, it creates vacuum to draw fuel; releasing it lets fuel flow downstream—perfect for clearing air or maintaining prime after shutdown 

✅ Key Features:

    • ✅ Dual check valves ensure correct fuel flow and prevent backflow 

    • ✅ Enhances safety—no mouth suction or fire risk when priming 

    • ✅ Compatible with 1/4", 5/16″‑3/8″ fuel hose; includes barbed ends for secure fit

    • ✅ Ensures quicker starts by pre-filling the fuel pump/carburetor 

    • ✅ Helps diagnose fuel system issues—bulb that stays flat may indicate blockage upstream
