I fixed the fuel gauge problem and it was easy. All you have to do is clean the sliding connections on the 2 fuel floats.
Take out the rear seat, expose the both openings to the 2 floats, withdraw the left float but just lift the right to expose the contacts and get a cotton bud to clean the sliding connections on both the floats. They don't seem dirty when you first see them but when you run the cotton bud over them you get a black oxide on the bud which is affecting the fuel gauge reading. Only takes about half hour.
