Fuel low warning lit up with 3/4 full tank. I filled the tank, the light stayed on. I removed the sender and disassembled it and cleaned it. I got a little bit of the black crap out of it but nothing that could bridge the contacts at the bottom. I put it back together and the light stay’s on. Bummer. The fuel gage seems to be accurate, the 3 wires are good. Anyone know where I should look next?

@old_pat ,Pat, link below had similar issue and stated they had to add additional ground to back side of gage cluster. See link below for more info and pic’s. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. http://www.benzworld.org/forums/r-c107-s
