How does ezgo fuel pump work

As the crankcase runs, it produces a pressure at the bottom of the piston of the cart. This pressure is also known as a “pulse,” and must be balanced carefully to keep a golf cart running smoothly. As this pressure builds, it produces a power that goes through the vacuum line of the engine and to the fuel pump.
