Funny I just recharged mine today for the same reason and when I went to recover the Freon it was empty, so I pulled it down for an hour and let it sit and it didn't loose any vacuum so the tag said 2lbs 9 oz the low side port will be close to the drier and high side is near the expansion valve I added some dye and charged it up and works good so have to wait and see if it leaks anywear.
