Greetings!

Does anyone have suggestions for fabricating a do-it-yourself pressure source that can be tapped to apply measured pressure to set controls such as MBC, rough-calibrate boost gauge, etc? What's the home workshop equivalent of a Mity-Vac that creates measured pressure instead of vacuum?

Best idea I have come up with is to cobble together something that would screw onto a tire stem, with connectors attached to another valve stem at one terminus and the other leading to a stopcock and then to a vacuum hose. I'm sure it'll work but I'm also sure someone here has developed a better way.

I'm willing to buy a cheap dingus but the one I found commercially was well over $100. I don't see the need for spending >$100 on the part if I can fabricate it for <$10. (I'd rather spend the money on beer than a one-time tool, a sad fact but at least I'm in touch with my true values.)

Cheers!

Motor and tranny rebuilt last year. More fun than new. But she sits dreaming of the open road and I sit chained to desk. Sigh.
