I think that is out of a Medium Duty truck with the 5K tach.

We've had a few threads on these before... http://forum.73-87chevytrucks.com/smforum/index.php?topic=14637.0

There's a company that sells factory style tach's too.

They had two styles of vacuum pumps for the diesels. One was a belt driven pump the other driven off of the cam.

those are generally harder to find than the normal tach versions, question is, does it work? Those only came in 3/4T and 1T trucks.
