John, I'll send you a pic of my setup. I can't figure out how to just put a simple image in a reply. It keeps asking for a url and I don't have one for a pic. Not worth the hassle of trying to figure it out.

Save the photos to your comp and then choose "upload a file" under neath the "post reply" button...instead of choosing the picture/media icon in the options above the text area.

I had been looking at venturi pumps--the kind typically operated by a shop compressor, but if there's a small electric vacuum pump that will work, that's better. I'll poke around that thread for the part number. Thanks!
Here’s the pump I use, 0-12 Volts DC, 2.5 lpm x 2, dual pumps one on each side, 2.5 lpm is plenty to open your valve. You need a variable DC power supply to vary the suction.

Thanks dude! I don't spend as much time on here as I used to. Excuse the window sill. Moving things around and it's a bit messy.
