Here's the URL to Jake Russel's website.  He documented how to change a
VW gas tach to diesel.

Here's another option I came across as well, make your own sender for
the tach:

I personally have been exploring the idea of using a tach from an A2
Jetta TD.  It's been sitting on my desk for a week now, I just haven't
had time to take apart the van and see what I need to do it.  Maybe I'll
see if I can find a spare cluster from another vanagon to play with.  My
van is the only thing I have to drive right now, so taking it out of
commision for a day or two is not an option.
