I just bought everything for mine last night. I'll be aiming the oe plastic elbow coming right off the unit on the valve cover right at the degas bottle...then using the factory rubber elbow into an adaptor from home depot to go down to 3/4" (the size of my check valve for running it into the exhaust) ill then simply route the home depot hose along the factory heater hose, then down the passenger side of the firewall perhaps by the HVAC box, and then into the exhaust ccv check valve I got for like 30 bucks at summit. That way, fumes go out with the exhaust, and never know about it.
