Firewall forward components underway

First two heater system SCAT hoses installed. Still need to run a bead of RTV down each one.

Duct tee installed. It looks so benign, so harmless, but it’s one of the toughest items to install that I’ve yet encountered, especially the inboard side with the spacer tube. Just…ugh…

Two of the heat shields installed. These will protect the fuel flow transducer and fuel hose from the exhaust pipes’ heat. Theoretically.

The third heat shield installed. This one will protect the throttle cable (not yet installed in this photo) from the exhaust pipe’s heat. Theoretically.

Prop governor cable bracket installed.

Oil breather hose and tube installed. This was another unexpectedly challenging installation. The two Adel clamps on the firewall – especially the lower one – are a screaming BEAR to get nipped up tight. Eventually, a little help from my wife and some ingenuity with available tools won the day. As usual.
