This is quite funny actually i just did my PT cruiser today at school and got a few good looks from all the smoke, but anyways...

It says you can pour it through your throttle body. I don't recommend doing such as it screwed with my cavalier when i did it the first time around. There is a nice big black plug that goes into your brake booster and its hooked to your Throttle body. Use that as your vacuum source as its the biggest and goes to all 4 cylinders. I would recommend getting an adapter that will allow you to down size into a smaller hose and not suck so much at a time since it will stall out your car. I used a once piece vac adapter with tappered ends. Stuck one into the hose after i remove the fitting and the other i had some small rubber washer fluid hose. Do this with the car warm and slurp the seafom up with the smaller rubber hose. Don't fully submerse the hose into the container. You'll have to rev it a few times while slurping because it will try and die.

Hope that fragment of an explanation makes sense.
