93 M20J 28V Fuel Quantity Gauge Needed

[Peter T]

I have been chasing a malfunctioning right fuel quantity gauge in my 93 M20J. It typically starts indicating correctly at the beginning of a flight, then after perhaps 15 minutes it will drop down to a lower indication and some minutes after that it will drop right off , as if all power was turned off for it. We have done some checking of electrical connections and ground etc. When I swap positions with the left fuel indicator gauge, the right gauge malfunctions the same way in that location, whereas the left gauge functions normally in the right hand slot as well as the left. This leads me to believe that the gauge itself is malfunctioning.
Does anyone have a functioning used gauge that they would sell me?

Left and right fuel gauges seem to be interchangeable, so I would consider using the left fuel quantity gauge part # 169-BH-910-3LBW and re-labeling it.

I have one it was working fine. I'll take $250.00 but I would like your old one.

Is the last letter in your  pt no a ‘V’ not a ‘W’?

I am pretty sure it is a W. It's hard to see in photos.

Part number for the left is 169-BH-910-3LBW; the right is 169-BH-910-4LBW.
