Fuel gauge wiring question

I'm trying something to take @RedFish 's method a step further. Instead of tape, I took a piece of plastic cut from a milk jug and made an insulator.

Here you can see the metal grounding tab on the back of the fuel gauge.


This is the area on the cluster housing that the gauge grounds. The white reflective paint appears to have been ground off to make good contact.


Here's the plastic insulator in place.



Thanks, Redfish! I've learned a lot from your posts. I'm sorry to see you've been posting here less frequently of late.
