Hi Dave. Here are some pics. There is about 1 1/4 to 1 1/2" clearance between the bottom of the AN4 elbow and the cowling. This is on a -7, so I'm not sure exactly how it will apply to the 8, but I don't suspect it will be that much different.
The FT-60 is suspended and not hard bolted to the engine case. It just floats between a set of the adel clamps. The hoses are some that Tom at TS fabricated for me. There is silicone tubing on the back of it to separate it from the engine, and this silicone is zip tied using high temp teflon ties to the FT-60 mounting holes. In hindsight, I should probably have a fire sleeve around the FT-60, but to be frank I made the outlet hose a touch short and I was going to have a dog of a time to get it to fit, so I will see how things go regarding vapor lock.
