Applications

Essential fuel system component for outboard engines, portable fuel tanks, and marine fuel line installations. The primer bulb removes air from fuel lines and primes the fuel system before engine starting, ensuring reliable engine operation. Regular squeezing of the bulb until firm indicates the fuel system is properly primed and ready for engine start.

Ideal for fuel line replacements, new fuel system installations, portable tank connections, and routine maintenance. The primer bulb should be installed with the arrow pointing toward the engine to ensure proper fuel flow direction. Replace primer bulbs when they become hard, cracked, or fail to maintain firmness after priming.
