skunk2 intake manifold

i just got my skunk2 intake manifold in the mail. well i thought it was 100% bolt on. its for a 2000 civic si dohc vtec. its all bolt on accept for step three in the istallation process. its reads as follows. for 99-00 civic si: to reconnect the EVAP valve hose to new manifold, it is required that a 1/8-pipe tap be used to re-tap thread the sensor bung located on the #2 intake runner. place a 1/8by3/8 bung fitting to reconnect the EVAP valve hose. well thats it so if anyone has done one of these before can let me know what this means. i think its just one of the metal connectors to hook sensor hoses up to but i'm not sure. thanks
