Electric fuel pumps generate a pressure that varies from 20 to 70 psi. In electric pump systems, the voltage transmitted to the fuel pump is monitored by a Fuel Pump Driver Module or FPDM. Marine fuel pumps are necessary for engine operation. 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. Warranty for 12 Months. Professional Installation Recommended.
