checked the grounds and all seems good, by grounding out the sender I can get the gauge to pin to empty. Sender reads around 30 ohmz (my tank is about empty). The gauge wiggles a little when I start the truck or turn on the ignition.

any other ways to check whats going on? right now I figure I need a new sending unit, am I right?
