Below a heat deflector is mounted above the port exhaust pipe.
I planned on doing a flight test but only got as far as the runup area when my fuel pressure was dropping down to .2 pounds from the normal 2.5 to 3.5 pounds. The tower controllers allowed me to backtrack on the taxiway quite a ways as I made my way back to the hangar. A couple of builder friends came by to give me some feedback on my fuel lines and the possibility of high heat causing vapour locking in the fuel lines. It was recommended that I shorten the two fuel lines as short as possible then wrap them in a reflective heat blanket material on top of the fire sleeve. They also recommended that I build 3 separate heat deflectors to clamp onto the exhaust pipes in three locations, two close to fuel lines and one to protect the starter and alternator.
