My Thunderbolt IO-320 arrived and has an Airflow Performance purge valve installed. I understand the need for the purge valve and how to plumb it for an RV-9A. A big thank you to Tom at TS Flightlines for answering my noob questions. Also, thanks Kyle at Airflow Performance. I am trying to find the best location for the purge valve return line bulkhead. From what I have read on the forum, higher is better to prevent fuel from flowing freely into the hot side of the firewall through a damaged return line. If you installed an AFP purge valve, where did you locate the firewall bulkhead?
Thanks for any information, advice, pictures, or general comments.
