Gauges

What you pointed out is a noise cap' . They all have that. Your limiter is inside the 3 post fuel gauge.
All 3 thermal gauges operate on the same limiter no matter where it is located. Reads like your original limiter is working since you didn't mention issues in the oil or temp' gauges.

THIS!!

There are bullions and bullions of posts on gauges on this site



If you are sure that the other gauges operate correctly......AND......reasonably accurately, it might be problems at the cluster connector (loose pins) a bad trace on the board, bad connection at the gauge studs, a bad gauge, problems in the wiring path / terminals to the sender, OR THE SENDER ITSELF which far and away is the most likely suspect

you can use resistors to check gauge accuracy, by substituting resistor for the sender



Hey Del, Look what I found!!! An original Miller Gauge tester!!!
