Answered: Pressure gauge on pneumatics

I was wondering if it is comp. legal to install a tee on the tank to install a pressure gauge to be sure of proper tank pressure. I have a pump with a gauge but the moment I release from the valve I loose a little bit of air and I would like to know the exact pressure I have so I dont make any costly mistakes come tournament time.

Since VEX does not offer a pressure gauge this would not be legal. The only legal pneumatics components are those offered on
