Can someone please tell me the direction the arrow should be pointing on the pcv..does it point to the tank or away from the tank...I took it off and just as I was doing so I had to deal with an issue and forgot to pay attention and I need this thing together and running tonight...it's my ride to work

Blow through it. The side that lets air flow will be the one that goes on the engine. The side that doesn't will face the air.
