Livorsi Gauge Problem

[NeedlesRat]

Yesterday, the fuel tank switching unit wasn’t working along with the gauges. Today, the fuel tank unit works, but above 3200 RPM the gauges start bouncing around and are all incorrect (GPS, RPM, Fuel level, water temp). It’s for my Stoker with a 280 offshore sport. I’ve never had this problem before, it all started yesterday after getting fuel.

Anybody ever have this issue or have any idea what could be causing it?

My Experience has been erratic gauges is most always a bad ground. They all usually share same Ground.
