Greetings from Germany 
I got myself a Tuxing TXES021 Compressor a few years ago.
I just cleaned it and replaced all the old gaskets.
i also removed the airlines and those brass fittings that where super duper corroded

behind one of those fittings was a lil spring hidden. but stupid as i am, i forgot where. -.-
unfortunately i can't find a exploded view for the tuxing compressor and tuxing itself doesn't answer me
