Well I'm an electronics tech so soldering is second nature to me. Originally when I got the car the stock sending unit had all sorts of problems. It was leaking around the 5/16 outlet and the phenolic board inside had become detached from the electrical plug. I fixed that all up, but I was able to do it at my leisure because I had access to other cars. Not the case anymore.
What I did wasn't that hard though. Anyone with a soldering iron and some time could do the same. Even if the phenolic board wires are completely toast, you can always get new wire and wrap it yourself.
