It ensures a consistent flow of fuel from the tank to the fuel injectors, helping the engine start smoothly and operate efficiently.
-
Typically constructed from high-grade aluminum or durable composite materials, the fuel priming pump offers excellent resistance to corrosion, pressure, and vibration.
-
It can be manually operated or electrically driven, depending on the system design, and is equipped with seals and valves to maintain pressure integrity and prevent fuel leakage.
