Actually its reguarding the vacuum check valves on the drivers side of engine. I was checking and replacing some hoses and got the direction of the check valves mixed up. They have black/white sides and I don't remember which way they face. I have one going to the vapor cannister with the black side going to the cannister. The other is right next to the EGR valve with the black side facing the front of the car. Is this correct/incorrect? Please set me straight.
