I get most of my ML stuff at Dixie Gun Works. Here's the link to their flushing kits page. Dang... It's been a long time since I priced them. They're freakin' CHEAP! Forget gluing aquarium tubing to an old nipple. First thing I've found since getting back into ML'ing that's less expensive than I remember it being. Sheesh!
