I’ve had a pump put out low pressure and it was a brand new pump at that. Only get ac Delco pump or swap the pump itself out for a walbro or the new Holley in tank pump and sending unit for our trucks, the fuel pumps are the weak point in these trucks.
Pros: new pump, low pressure
Cons: fuel pumps weak point
