Quick Drain Oil Funnel for Lycoming Engine

Funnel for draining the oil on a Lycoming O-320-E3D with the quick drain type oil plug. I designed this for my Piper Warrior PA-28 151. I think I used a 3/4" hose on the barbed end of it. I run it out of the bottom of the cowling into a 1 gallon oil jug. It's designed to hang onto the little bars that stick out and lock open. I tried several smaller versions but I ended up needing it this size so the oil wouldn't overflow the funnel area. I had to heat up the end of the hose to get it soft enough to slide onto the barbed end.
