Paul,

Here are some pics with the fuel plenum and proximity. Both pipes will be
routed into the metal duct, turn up, then rearward.  This is a mockup
engine.

A substantial heat shield will be required.

That is a cool exhaust flange Joe. Did you make it or did you buy it?

Are those p-port tubes aluminum and bonded in?
As I recall you had a lot of trouble sealing those.
I did too on the first p-port engine I built.
The new SS welded in tubes are a lot easier
to get seal. Inner and outer seal.
