Sooooo,

This 'pulling a vacuum'- It makes no provisions for recovery of existing
R-12 in the system. I have a GTi with A/C, I wouldn't mind capturing
what's in there, else I have to do some crazy stuff to get it out in one
piece.

On the other hand If I can't get the R-12 to a certified recovery agent
then I could just vent it but I loath to do that to Momma my Earth. I
have been looking for a way I could capture the stuff into a propane
tank for the time it took to remove the system and reinstall it w new
dryer in another car.

In any case, I believe I will put myself on the (wedding) registry at
Harbor Freight.

Thx for the update,
