Grounding of the sending unit is tenuous at best without a direct hard wired ground connection. On our ?55 C-300, the sending unit is accessible via a hole in the trunk floor. I removed the sending unit, drilled a small hole through the top plate of the sending unit and through part of the base plate of the resistor/float mechanism, inserted a small bolt, secured it with a nut and lock washer, set in epoxy (for a seal) on the top. The bolt being long enough to take a ring wire terminal and another nut and lockwasher. Ran a wire from that bolt to a bolt head on the trunk lid latch at the rear of the trunk and got a good ground. The sending unit had been rebuilt poorly with a replacement resistor and slider, but it works and jiggles all the time. Still struggling to find just the right O-ring to establish a tank to sending unit seal that will not dissolve from the current formulation of Flock Juice in the tank. BTW, the sending unit is date coded on the bottom 1 55. Sounds about right for a March 1955 Baby Brute.

The factory grounding strap has one ear broke. I have used a cloths pin on it to make the connection the last couple years. This year I decided to ground the tank lip to the frame. Now the gauge does work but it reads l/8 full and I believe the tank to be over 1/2 full. Does the grounding need to go to the nipple coming from the pickup or should anyplace on the tank work?
