i have a 2000 s-10 bagged that i have two 12v comperssors this past summer one burnt out so i am going to dump the 12v and go edc i was just wondering if any knows if you can make the stock a/c pump do air, i messed around with my it pumps a ton of air but will only build about 20 psi i did not if there is a internal check valve that could be reomoved to build-up the psi. if any has any info it would great if not i just by a york and put in place of the a/c pump thanks.

I'm surprised you even got 20 psi out of it.  Sanden and York A/C comps are the only ones to my knowledge that can be turned into air compressors.  The S-10 comes with neither.

my buddy runs his ac pump for a compressor on his mazda b series, it compresses his 12 gallon in about 2 minutes, its just whatever pump that came on his truck could be a york or something like that but i dunno

Most likely a Sanden.  I visit the Mazda boards every so often and I recall that the B's had Sandens.

don't mean to ask a dumb question but how do you regulate these ac compressor pumps to keep them from pumping when the tank is full? can the pressure switch flip the compresser on and off like the AC?

You connect the clutch wire of the compressor to a pressure switch just like you would connect a pressure switch to a relay for electric compressors.  When the pressure switch is open, or not on, the clutch has no power, and thus the compressor doesn't pump (similar to turning on and off your a/c).
