I got a ford tech to replace my bypassed heater core and to convert my AC to the new style the other day for pretty good price compared to what all Ford Dealerships were quoting me. However, after he drove it he told me that my fuel pump was probably about to quit. He said it was very loud and was about to quit/ need replaced. It seemed like every fox that I have drove had a loud fuel pump. Is it true that the louder the fuel pump, the less life the pump has in it? I thought it was really loud myself, but I thought it was normal/ hatch back letting in extra noise.
