    Separated fuel level sending unit

    Somehow while my fuel sending unit was sitting in a box, the arm assembly became detached from the backing plate. I don't see how to re-attach it. Am I missing a piece? Anyone have a pic showing the correct orientation? Should I solder it on?

    Looks like a couple of broken spot welds.

    Not sure that soldering would work, but brazing would.

        I don't have access to a mig, and I'm worried about the wire for brazing. Would JB weld be a good alternative?

          It's an alternative but I wouldn't call it good. A couple of tacks with a welder are far better than smearing on some goop but if it's what you have then JB Weld is at least resistant to gasoline. Worth a try, and if it doesn't hold up no real harm done.

            JB will eventually soften and fall away. If no MIG then I would clean the metal very well with steel wool, wipe on some soldering flux and solder it together. That or im sure someone you know can give it a few spot welds with their welder.

              Silly me. I took it apart so long ago, I couldn't remember how it was. Turns out this unit isn't like the one on my 850. The float arm isn't even supposed to attach to the plate. The float arm bolts to a plate inside the tank. I looked at 3 or 4 of them that were on e-bay. They were all separate like mine. Parts fiche drawings show them separate too, along with 2 screws and lock washers. . That explains why I couldn't find any witness marks showing broken spot welds.
