Norcal49er, thanks for the info. That will be an easy check and is definitely the way to rule out guage or sender. I would really like to see a schematic drawing of this unit and guage but have looked everywhere on the internet and just can't find one. My bet is the float is stuck. Based off of your info, if I had a wire shorted then I would read empty all the time. But as soon as I turn the switch the need bounces off of full. If the float is stuck, is it as easy and just removing assembly and freeing it up. I am sure I will need another gasket to reinstall.
thanks
thanks
