Krypto, that's a very neat pressure gauge on the Jensen in the video.

Where did you source that from?

Well that adapter was someone else's idea that I copied from a picture in the old forum.  The small gauge seems to be very difficult to find now at that pressure range (0-30 PSI).  McMaster-Carr quit carrying them awhile ago but I was able to find a few on Ebay at some point.

It's a handy device because it's so easy to move around from engine to engine.
