I have the K Jetronic tester from BMP for the I5 CIS fleet:

arch_model/11

and it has all but one fitting to test the Motronic on the V8Q (which I
THINK might have the same fittings as the 20V.)
I took the gauge hose and a bolt that fit into the cars pressure line to
the local tool rental place, they had a fitting that matched up
perfectly, I think it was part of a pressure washer or a steam cleaner. 
Equipment rental places and hydraulic shops usually have a pretty good
selection of adapters.  I did use the CIS fittings that came with the
gauge too, so if your gauge doesn't have these I don't know if you'll be
able to find them piecemeal should you need them.

I live on a one-way street that's also a dead end. I'm not sure how I got
here, or how I'm going to get out.
