I'm wanting to pull the vacuum line from the top of the power brake booster.
 

I want to install something behind it and removeing it seems like the best way to get behind it. i pulled it slightly off at an angle and i could hear the air running out of the line. if i take it off and then put it back on will the pressure build back up when the car is started? its the black tube the runs from the top of the power brake booster in the engine bay. (drivers side near firewall-looks like a big round disk on its side..)

Yes, the pressure will build back up when you start the engine.
