I'm installing the unheated Garmin AOA pitot using a Gretz mount in my flying RV-8A. The existing pitot is the bent tube that I assume was standard in the circa 1998 kit. It attaches to the hard line with an elbow, and exits the wing into the airstream just forward of the middle inspection plate (bell crank access) adjacent to the forward inboard corner of the plate.
Question: Where should I install the new pitot? There is some consideration of potential interference with the tie down eye, therefore should I move the pitot to the vicinity of the inboard inspection plate, or is that too close to the prop wash?
Question: Since this is a retrofit, should I drill out some rivets and try to fasten one side of the doubler plate to the rib, or is it OK just to use the doubler on a field of skin without attaching to some structure?
Question: Generally, what color tubing is used for the AOA and pitot lines?
