The PURGE valve is on the vacuum rack and is plastic. It has one small vacuum hose on top and two plastic nipples on its bottom. ONE is larger than the other and THAT might be where your open HOSE should go to. The PRUGE valve is to the rear of where the oil fillter tube is or.......on the rear half of the vacuum rack.

Purge valve looks like the one shown in the online factory service manual in the section Fuel and Emissions.

I think I can spot it in one of your pictures just infront of the Blue duct going to the intake elbow. Black..........plastic.

OR they might have removed the Purge valve in order to install that aftermarket intake duct......then there'd be no place for the hose coming from the oil filler neck to the purge valve.
