Induction duct diameter

[Martin S.]

Evening gents,

I plan to replace the hose that attaches to the induction air system with a fresh sceet duct. Does anybody know the diameter? I couldn't find it in the IPC.

Many thanks,

Martin

2.0" dia x 22.0" long. The one between the muffler shroud and the firewall valve is 2.50" dia x 33" long. I ordered SCEET (double wall silicone with finished ends) from @Gee Bee Aeroproducts and it will last longer than the engine.

Black sceet

Finish ends

Breeze aerospace lined clamps

Thanks Skip, ordered the material right away — the lengths fit perfectly.
