I just recently bought a 95 vert, 3.4L. The fuel gauge seems to "float." When accelerating it goes up, when idling it moves back down. I can't seem to get it to sit still. Anyone have this issue? Could my sending unit be bad? Could I have a leak somewhere? I can't seem to get an accurate reading - though it does progressively move towards E - it still pops back up upon acceleration. Thank you for any help.
