so I said I wouldn't but I did.....I bought a can of gas and a hose with
a meter...connected the can without piercing it and connected the hose
to the schrader valve and the pressure was up in the danger red
area....I then started the engine and I could hear the compressor coming
on....so what could be the problem?... looks like I have wasted my
cash....suppose I should have pushed the schrader valve before I bought
the stuff....
