Randy where is the sending unit/float located in the tank, that works your fuel gauge, I have a '96 and I'm not getting an accurate reading, while you were in there do remember what side, of the tank it was on
Let me rephrase, the filter was on the right and the pump was on the left. As for the solenoid, I didn't replace it, but it was nowhere in the tank. Hope this helps.
