    Have dropped gas tank on my '90 Jimmy to remove for repair. How does the wiring for the sending unit disconnect?

    I am not sure if this will help. I check my 75, and my 83 k20 diesel for the wire mounting. Both only had a brass stud that was mounted to the sending unit. The wire terminal just pushed down on the stud. The tank to the K5 is out of the frame, but the k20s tank still had the wire conected. I had to lightly pry it up off the stud. Since you`r `90 is EFI things could be very different though. Good Luck.

    Thanks for the reply, but mine is different than that. Three wires going into a plastic connector on the sending unit. I know I can cut them, but I would rather ask than be sorry I didn't.

    There is a disconnect by the frame and you also have to take a ground of the frame in the same general place. You should not have to cut anything just look around. - Doug

    Thanks Doug, the plug was covered up by mud, I just didn't look close enough.
