kinda ghetto "pull on the spring to make it stronger" ! i like the good ol vfaq one better...

Did I read through too fast, or did they leave out a part regarding "locking" it when you find the setpoint?

I guess with the vac lines clamped on each side it won't turn very much. I don't think the vac lines are gonna spin around. I'd sure like to see one work though. It just looks to easy. What about the little hole your supposed to drill in it like the one on the vfaq?

Ah, so long as it's not going to turn "very much".... eeeeek! No, I'd say at least a couple drops of Locktite.
I don't know what to say about the missing vent hole. Maybe those open brass threads compensate for it?

Very similar to http://www.dawesdevices.com/boost.html

I made one like that, it does work the same as far as pushing tension on the spring/ball, but there is not vent hole? I never did install it or use it.

Egad, $42 bucks? He's better stop by and put it on for me, and wax the wagon in the deal. That's quite a markup for an $8 checkvalve (McMaster-Carr 48935K25 http://www.mcmaster.com/ ) and a couple of barbed fittings.
