The sending unit in the 50 has never worked (maybe electrical?). Nevertheless I noticed that the unit in the 50 is like a worm gear type with the ballast being connected to one gear (in a vertical position) meshing another gear which is in a horizontal position that is connected to the long shaft up to the top.
The unit that came out of the 53 has its ballast connect to a different type of pivoting mechanism but also has a copper like ribbon which runs parrallel with the long shaft up and down.
Can I use the 53 sending unit in a 50 truck ?

Take an Ohm meter and connect the negative lead to the sender housing and the Positive lead to the center terminal and move the float arm through it's travel range and record the reading. Test both and if their both good you have a similar reading. You could also find a bad sender by testing the senders in this manner. What I also do is connnect the hot wire to the sender terminal and take a jumper ground wire and connect one end to the sender housing and the other to the truck metal. Turn the key on and move the float arm through it's range and you should see the gas gauge needle moving.

Just my two cents.
