Hi - I"ve been having some issues with the fuel gauge and decided to have a look at the fuel sending unit inside the gas tank of my 65 230sl. It actually looks pretty good for not being touched for 50+ years. There was what appeared to be some crud on the inside, a flake of which was preventing the float from descending to its lower position. Problem solved. But the closer I looked I saw that the third wire inside the unit was broken. This is the almost spider web-thin wires that are within the unit itself. There are two across from each other that appear to guide the float, and a third wire, which is the one that's broken. Rather than buying an expensive new unit, is it possible to solder the wire back to the contact? Thanks in advance! --Kris
