???? not fast enough.... i have my factory a/c comp. set-up to pump air (was taken apart and filled with grease, link to the how to click here ===> )... i have a 5gal tank.... it fills it from 0-200psi in less than a min. at idle there's NO 12volt compressor on the market that runs air that fast.... there is a tag on the compressor that should say Sanden and a number... either 508 (5 piston comp) or 708 (7 piston pump)... i have the 708... from what ive read the 508 is a little slower but still faster then any 12volt comp you can buy.. also do you know if the previous owner converted the comp over to greese or just hooked it up (because i dont see an external oiler).... if its not properly lubricated it will burn the piston rings up(which are similar to the design of an engine piston)........... also just an fyi if you plan on tapping the back plate on the comp im going to suggest you get either a compressor leader hose (braided hose) or a high temp hydrolic hose because the comp gets really hot!! also i noticed it looks like the previous owner used what appears to be hardware from a hardware store (that is ment for water use, im a plumber of 5 yrs and we use them daily for water, the fittings have metal ferals in them which cut into the plastic air line and over time you may develop a leak) for a more reliable (non leaking and long lasting) set-up id suggest looking into some DOT approved fittings which you can buy online.
oh and btw my back plate is tapped to 3/8s with 3/8 line coming out of it all the way to the tank, i got an oil water seperator about 3 feet from the comp. on the fire wall and from that 3/8s to a 1/2 check valve that is threaded to the tank
