That's not a vacume port. your going to have to replace that piece you broke and reinstall the spring and plunger. this is part of the drive by wire assempley on the side of the throttle body. you should be back about six inches where the vacume used to go to the drivers side pcv valve, the pcv valve should be capped off and the vacume block tied into the bypass valve. the block should have a 1/4" plug in it you can remove or the gauge came with a tee fitting you could plice into the hose running to the bypass valve.
