Installed oil/air seperator high on copilots side of firewall. Removed a 3/8 NPT brass plug just below the accessory pads and replaced with a 1/4 inch barb fitting for oil return. Used 1/4 inch flexible fuel line from fitting to seperator. Routed breather line from oil fill pipe, through a grommet in a hole in plenum, to the seperator. I used an automotive 3/4" id heater hose for this and it is a no go because of kinking. See photo 3 below. Another order put into spruce for some mil spec stuff at $7+/ft.
