just got my bluvac yesterday in the mail. busted it out and was playin with it just pulling a vaccum on a 5foot hose with the gauge on the end. i can't get it too hold a vaccum. no matter what i do. i've tried just a hose and using the pump to blank off then i tried my manifold thinking my pump might have a small leak. but it still just keeps climbing.
I know ain't it cool!! Did you expect something different?

Could be dirty or most likely residual gas or something beside air is in the sensor cavity still. If you blow at the tip it will clear very quickly.
