i tried to the other day but i couldnt get the tube to go down once it went inside the supercharger. i am sure not the first one to figure this out but i thought i'd post up some pics in case some of you haven't seen it. i took some 12 guage copper wire, not the stranded stuff, the solid kind. i stripped the wire off of it and put it into the tube. i bent it at a 90 degree angle about an inch in and then fed it into the hole and down it went. i held the tube in place and then pulled out the wire. then i just hooked up a syringe and sucked out the old oil. i think it took 10 minutes tops. like i said, i am sure this has been done before.
