Hi,
I was told that the Ford original fuel pump in the 92- 96 years needed to be replaced well before the normal 100,000 miles, like around 40,000 miles. I have a 97 and is still the original pump at about 56,000 miles.
I would recommend changing the pump. Some install a external to the tank pump just because it is so difficult to remove the tank. Yet it can be done at home. It helps to have a floor jack and several motorcycle tie downs that have a ratchet to tighten and hold the tank into place as you bring it up with the floor jack and a 4X4 about 4' long to distribute the weight to the sides of the tank.
I need to change out my tank pump and sending unit, mainly because the sending unit is bad.
Fred.
