Lately my fuel gauge has been acting up. When I top off the tank, it will read 'full', but after driving about 50 miles, it'll drop completely down to empty. Do I need an entire new fuel level device, or is there any serviceable part I can replace? I don't see anything at all in my manual about the level sending mechanism. It would be nice if some contacts just needed cleaning, but it would also suck to get it all torn down only to find out I need to order something. :)
TIA
