Just pulled the unit out of the tank, hooked up just the sending unit to the pink wire and grounded it turned the key on and moved the float up n down and gauge working as it should, but when I pulled it out it was stuck in the full position is it any way to spray that with some type of lubricant? Probably not because it just sits in gasFor sure, the Spectra Premium unit I got through the dealer was easy to find 2 years ago. Now it's difficult and I don't blame ya.
Anyway, like 69hurst said you can repair it yourself. But if it was a new unit, I really do think it's the wire that runs to the gauge cluster.
