I've considered running a 3/4 inch line all the way back to the tail and decided that there would be too many holes and a lot of weight. Some folks have run a line down to and almost touching the exhaust pipe near the cowl exit. This method is simple but I think with a quart of oil exiting the tank, a lot of smoke and fumes would be generated, not to mention a potential for fire. I'm thinking the best way to go is to weld a short piece of 3/4"SS tube at a 30-45 degree angle to one of the exhaust pipes and hook the hose to that. My concerns are one, what happens in the event of a backfire? And two, how hot will that SS tube get that is attached to a hose, IOW, will the hose withstand that kind of temps. Thanks, Jim Stone Louisville ________________________________ Message 2 _____________________________________ Time: 12:41:52 PM PST US From: Weasel Graber Subject: Re: Rocket-List: Inverted Oil system overboard line --> Rocket-List message posted by: Weasel Graber Hey jim i have this set up in my rv4 and it seems to work 4 me the only diff is i dont have an inverted sys i just ran the breather into the ext.

I just ran a hose out near the exhaust. it hardly has any oil film on the inside of the hose. I really dont loose oil through the breather.
