Not sure. They consist of a wiper on a resistance element. Since it’s submerged in gasoline I would expect it to be pretty robust. Other than some corrosion from condensation on the case that covers the resistive element everything was in good shape. In an earlier blog post I detailed removing and repairing the sender, as the pivot was stuck in place due to it just sitting for a long time in the top of the tank without being covered in fuel. I suspect there was condensation that formed in the top of the tank which caused the corrosion.
After removing the sender and soaking the pivot with some Kroil it freed up easily. I don’t recall how the pivot was secured, but I didn’t try to disassemble it. I just put a few drops of light oil on it and moved it around a number of times to make sure it was moving freely. I also hit the resistive element and wiper with some DeOxIt fader cleaner. Replacing the cork gasket was a big win, too, as when I went out in the garage this morning I didn’t smell fuel. One thing I mentioned in the blog post was that the cork gasket holes, despite looking that way, were not symmetrical. I found out the hard way because I just pressed it into place and it was clearly not right. I gently removed it from the tank and used the gauge sender flange as a reference, turning it to line up the holes. They only matched exactly in one position. -D > On Jan 10, 2019, at 6:51 AM, Dimitri <dsereta...@yahoo.com> wrote: > > That detail stuff is fun! What was the condition of the sending unit?
