Fuel gauge scramble

[Green Machine 79]

Just in case anyone comes along this with the same issues in the future, I'll admit my embarrassment..

After replacing a completely broken sending unit with no change to the gauge, I shorted my circuit board trying to ground the wrong prong of the fuel gauge. (Hint: it must not be the bottom one)..

After replacing the board, I still had no change to gauge. I was planning to rewire the sending unit to the firewall but was confused on how to do that. So in my few moments of considering how bad that could turn out, I noticed my tank selector switch was set on the driver side which has no tank.. I had let my youngins play around a bit some weeks ago while working on something else.

So, a hundred dollars late, my fuel gauge is great. In fact, I just filled it up and was surprised to see a full tank stops the gauge directly on the full line.. I didn't expect anything from oreillys to be so specific..

Thanks everyone for chiming in!
