VDO fuel level sender unit

In this video I open and repair the fuel level sender unit from 82 380SL Mercedes. The same principals apply to lots of other models from mid 60s to early 2000s.
When soldering, the resistor wire can be taken of the bottom tensioner to allow for some slack.

What type of wires are those that the floater moves up/down on? The ones on the sides. Are they resistance wires? How many Ohms and what gauge are they? Anybody knows?

Ok guys before you purchase a new fuel sending unit try and clean the electrical connection on top of the unit first. Don't make the same mistake I did, and purchase a new VDO sending unit which didn't solve the gauge Fluctuating issue. I took the old one apart, and cleaned it up well put it back together and used a 220 grit sand paper to clean the electrical connection on the sending unit. It works perfectly fine now.BTW it's a 1995 E320

Thanks for your video, but you should do it again and show more details, slowly... I'm working on my 74 230 and found the thin wire broken, but was not sure how it snaked around till I think I saw this video... please show details slowly next time... Thanks, VW
