I've googled the heck out of this. I even took off my PS headlight and there is absolutely nothing resembling the low pressure port. Where exactly is this low pressure port. I have a 2002 9-3 SE. I feel so stupid. I'm all ready to roll with recharging this puppy and I can't friggin find this valve. Someone have any pics to show. Would be gggrreaaatttllluy appreciated.
