When I had my 1989 F150 with dual tanks, I could never depend on the gauges. When you change the gas tanks.......and you will, you may need to replace the fuel pump/gauge float in the tanks too. In my case the front tank leaked first. 4 or 5 weeks after changing the front tank, the rear tank started leaking. The rust on the whole tank was real bad.

We cleaned up the front fuel pump assembly as best we could with a small sandblaster and reused. Replaced rear fuel pump assembly with some sort of rebuild, and if I recall correctly; neither worked the greatest. There must have been a bad common ground wire somewhere that needed to be cleaned up and got over looked.

I would set the trip odometer at zero on a full tank and top off at 200 miles. It was just a method that I used on my 86 F150 and 86 Bronco for many years. Even from the factory my 86 F150 fuel gauge was unreliable.

So, to answer your question, There must be a bad common ground wire somewhere.

Hey, as I've stated before, I've seen it all. When customers have their vehicles towed in because they're out of gas, then ANYthing is possible.
