Finally I'm done with the engine oil lines, I think. Re-made the tank to case vent line to replace the faulty flares and improve my chances of no leaks.
Also changed the 45 degree AN elbow that is on the case end of this line to a 90 degree because the kit was short one 45 and I had an extra 90 because I ran both scavenge return lines to the tank instead of Teeing them. I needed the 45 on the bottom of the tank where a 90 wouldn't work and the 90 worked ok on the case vent with a little extra bend put into the new oil line, and more importantly, I saved $6, that's over 5 minutes of fuel, when this thing finally gets to burn some fuel.
