Ford Super Duty 7.3L Powerstroke FREE Fuel Gauge Repair (Fix for FULL FUEL LEVEL all the time)

I am pretty good with electronics so, when my fuel gauge started getting wonky and then I received bad fuel, I dropped the fuel tank, and was going to replace the sending unit. However, I found that the part that Ford wants $750 for is extremely simple and I figured out, that, if you are running on a shoestring budget, like I was at the time (This happened in the middle of the Covid-19 pandemic) that it is worth a shot to repair your sending unit. If it's already not working, what have you to lose?
