Engines require gas to run, and fuel pumps supply that gas under pressure to ensure both smooth running and efficient engine operation. Boat fuel pumps convey the fuel from the gas tank directly to the individual cylinders. Note: If your fuel pump fails, you may notice starting issues, vehicle surging, engine sputtering, and poor gas mileage. An electric fuel pump can usually be mounted to the frame and wired to your ignition circuit to pressurize the fuel system as soon as you turn your key. Note: Please check the part number before purchase.
