I wanted to remove temp sending unit on a '96 2500 w/Cummins.  I know
where the sender is supposed to be but I can't lay a eyeball on it - it's
well hidden (drivers side rear below #6 valve cover).

I reached my hand in there and think I found it once but I could not
duplicate the feat later.  I removed the drivers side wheel liner but I
could not see it.  Crawled under the truck but I could not see it.

Help!  How can I get to this little beastie?  Or is this a trick
question??  :-)
