I just used a couple of brass fittings to allow me to drop in a couple drops of water and pull a vacuum on it.

It works great! It sure looks like this pump is going the job.. To some extent.

It was neat to feel the end cap getting cold as the vacuum vaporized the water.
It happens pretty dang fast, I was surprised.
I'm pretty pleased with the results. I can tell by the sound of the pump motor
when it's getting down to the last little bit of air inside the hoses, manifold etc.

I sure wish that I had a good gauge to see just how low it's getting.
But, right now I'm pretty sure this pump is suitable for this job,
even if I don't get the fancy gauge..

Since the Sanyo is going to be here Monday, I don't have a lot of time left
to be ordering stuff. Maybe I can find something local like you did..

I have had the hoses manifold under vacuum for the last couple of hours
and the compound gauge is sitting right there at 30 and not dropping.
And when I start the pump and open the cut-off, I can hear the pump
run fast for a few seconds and then go into labor as it hits the Hard work again.

I'm watching a VG200 on Ebay..

But, that thing is going to be on there for a week!
Have to check the local AC suppliers, if I can convince myself that I really have to own one of these things..

My problem is, I love gizmos..

Edit:
Fieldpiece SVG2 Standalone Vacuum Gauge: FIEL18 Climate Doctors
This one looks like a more reasonable price.. I've got some local distributors to call this Monday.
