DT466 parts ID?

[Clayton]

I am looking for a couple parts for my 1996 DT466. My local parts places cant help me as its not in "the computer". Does anyone have any part numbers in their manuals? The first is a sending unit. I think is for temperature but I am not sure. I broke it when I lifted the head in place. Its the top one in the photo, you can see it is just hanging on. The second is a thick odd shaped o-ring. Its on the tube that supplies oil to the turbo. See 2 photos. Thanks in advance.

I called Midwest when I couldn't find an elusive part. Gerald is awesome at finding elusive parts!

That seal on the turbo tube looks like the vibration resistant viton fuel line seals on my 7.3L Powerstroke. Check Dieselorings.com and look under '99 to 2003 7.3L fuel system parts. They have several different sizes available.

I found the seal at a Case International farm equipment dealer. The fellow there knew exactly what I needed as soon as he saw it. The part number is 222-154.

Nothing on the sending unit yet though.
