Here it is 1992 Bronco XLT, 5.8L, E40D, 180,000 miles. Everything work fine except for the fuel gauge. It started moving up and down the scale even though the tank is full. Settled out at 1/4 of a tank then moves up and down . Just started after a heavy rain. (Bad Ground?) Also seems to be affecting the oil pressure gauge it swung once and then worked fine after shut down and restart. I have a complete set of wiring diagrams for the truck and there are a lot of grounds to check.Has anyone ever seen this or has a idea on which grounds to look at first??

On my 92 F-250, it was the gauge itself
You have one gound to check on the fuel guage. The oil guage is on another circuit, one will not affect the other.
