Hey, Ive Got a Aircon Pump off a guy on here and another one hopefully coming (just in case).
So im about to put it back on the small port but noticed some black oily grit in the ports that the gas flows through the pump through. I dont really want to blow compressed in there because im worried it will blow into the pump...
Do i need to worry about it? I could spray some crc in, with the right angle im pretty sure i can get about 95% out and end up blowing the rest into the pump....
