I brought the fuel tank for the 961D back to town so that I could work on the component swap in the comfort of my shop. I can't believe what was in that tank. All of the brass components have a sticky green slime on them. The inside of the tank and the cap had a thick brown scale that looks like rust, but after scraping it, is definitely not rust. The bottom of the tank has about a half inch of gooey, sticky brown sludge in it. And the sending unit had a hard crystalline substance formed on it. Also, the surface of the plastic components of the sending unit were soft and mushy, as was the O ring at the fuel shut-off.
What the heck was in this fuel?
The fuel cap and the sending unit (see photos) were installed new in the winter of 2014.
I was able to do a close examination of this tank with it off the tractor. I think it is salvageable if I can get it cleaned out. Carb cleaner seemed to clean the parts pretty good, so maybe a long soak in a carb cleaner bath.
