I have one on my 94. I put it on with my fuel system. The sending unit isn't the same on the 94 as the later trucks. The bottom of the sending unit on the newer trucks is better designed to hold the draw tube in the center of the sending unit. I set mine so it would hopefully stay at the bottom, but I don't plan on runnig the truck under a 1/4 tank too often. You could probably look at getting a newer sending unit or parts from one if you are worried about it.
