Awesome find Burgess159! Here's what their website has as part numbers for the Coloranyon 2.8L
Saw this on the 2.8 LWN Duramax owners facebook page and thought it sounded like a great idea. I've never seen one. Especially since there is a cross member right below the drain plug on our truck that causes a heck of a mess when the oil hits it? Guess you change the oil once, then insert this in place of the drain plug. It has a little lock thing to hold the lever in place from accidentally getting opened somehow (wouldn't that be awesome, accidentally lose all your oil when a twig hits that lever). Also can get a cap to cover up the spout to keep it clear of debris. Just get you some 3/8 hose and then it all goes down the hose and into your train pan or whatever you put oil in. Think I'm going to have to get one.
