Kip,
Is it just a light press fit into the phenolic? Another advantage of my opportunity (having forgotten to plumb the wing and provide a pitot-static mount) is that stuff will not be in the way for installing wings.

Yes, Brian. The 5/16" tube slides (twists, really) into the phenolic as a tight "press fit". After drilling the phenolic for the tube, I found that I had to sand down the pitot tube in a lathe a couple of thousands for the right friction for a tight fit. I thought that if it ever became loose from too many in-and-outs, I could always count on getting a new tube and still have some room to adjust for a tight fit. My pitot still slides in with the same friction after six years.
I'll make a video later today or tomorrow if I remember...

Here Adam is copying Kip's idea. The tube I have on hand is 1/4" OD, same size as my ACS wing mounted pitot.

Sorry if I drifted from this topic. Let me know if you need more info...

No worries Kip! Any thoughts on my 1/4" OD vs your 5/16" OD tube? I am thinking it is unimportant. Also did you choose the RH side for any technical reason? Finally I assume the plastic tube is from Home Depot's aviation aisle. Plastic all the way forward?

Bryan, I have read that pitot tube diameter is not too important. Come to think of it, my tube may in fact be a 1/4. I don't remember.
All of my P/S lines and fittings are nylo-seal brand, I believe. It's all TSO'd stuff and has not given me any problems in over six years now.

I have to confess I am tempted to use poly tubing. Has anybody else used the stuff for this application? It seems to last forever supplying water to the fridge.

Kip,
What length did you settle on for your tube? Any science or experimentation to it?

I went with what looked "about right", Bryan.
That would be about 6 or 7 inches exposed and about 3 or 4 inches in the base.
If I remember, I'll make a little youtube video about it next time I'm at the hangar. Hopefully this weekend.
