Garmin adjustable pitot mount installation

[RichF]

Hello, I’m building a RV8 and plan on installing the Garmin adjustable pitot mount. I’m unable to find any examples of this installation on a vans wing and was hoping someone could refer me to a good resource showing how this was done. The Garmin adjustable mount is a two piece mount and isn’t riveted to the spar flange like many of the other mounts available. Garmin recommends it be mounted on an access panel, which I was planning on making one bay outboard of the aileron bellcrank. The additional access panel would be screwed to the wing spar flange with 3 #6 screws similar but smaller to the access panel right next to it. I haven’t cut any metal so I’m not committed this plan yet and would appreciate hearing about how others have done this installation. Thanks

I mounted my pitot tube on the outboard access panel, the one shared with the aileron bellcrank, but I offset the mount further outboard. See attached pic.
I bent both aluminum tubes to point aft then angled them to point at a wing rib lightening hole. Then I made the connection to the red and blue 1/4" plastic tubes, looping them into the next outboard bay before running them thru the wing ribs into the cabin. Think of a giant service loop.
Stein sells the 1/4" to 3/16" union to connect the aluminum and plastic tubes.
Note, I did this on my -9A which has 3 access panels per wing.
