chris you cant force freon. you need to "create a vaccum" like lrsc said or you need the compressor to suck it in.

i'm not going to bother a vaccum. i'm gonna jump the compressor and put my dye in. find the leak. and fix it. i have plenty of freon so i'm not wasting money. besides i know my leak isnt that bad. i'll get a whole summer out of the can and when i see the magical yellow stuff i'll fix where its leaking and be good to go.

thanks for the help guys.
