Hi John. My name is***** is the complete model from the engine tag and serial number of your engine?
Check between the tank and pump for leaks and restrictions and for proper fuel supply pressure from the supply pump. Depending on if you have a single tank or dual tanks you will have a transfer pump and yes there is an electric transfer pump. Check your fuses and relays and for power and ground at the pump for a possible faulty pump if there is power and ground but the pump is not working. Let me know
