Sorry Craig, I got the job done without your generous offer of help!
I used the "universal" sending unit from Jim Carter Truck Parts to replace the two year old and dead "universal" sending unit from Jim Carter Truck Parts. I didn't mean to order the same part that failed, I just forgot where I got the first one from and didn't realize it was the same part until I recognized it and checked my records.
But I know more now about electrical stuff than I did 2 years ago thanks to Jerry and others here on Stovebolt. My truck was converted to 12V before I got it and I elected to run a resistor in front of the gauge to lower the voltage. I tested the sender before I installed it and it looked good. I followed the instructions for adjusting the depth and arm length for my tank and just today I put in what I figured to be 1/2 a tank. Success! The gauge is pretty much dead centered.
The biggest challenge was that the hardware was clocked 90* off from what I needed, making it impossible to install. The float would be hitting the side of the tank and there would be no way to bolt it down. The only adjustment was 180* which gave me the same problem just on the other side of the tank. I ended up having to change the orientation of the holes in the flange that bolts to the top of the tank. I also had to cut off some length of the framework to allow it to wiggle its way into the small tank opening. Thanks to my paternal grandfather machinist's genes, I was able to figure out how to do both those little jobs, though I had to think really hard.
Is there any such thing as visual dyslexia? If there is, I got it! Thanks everyone, Jim
