Installed the pitot tube. It required a 5/8" hole, and the largest drill bit I had was 1/2", so I used that and enlarged it from there with the Dremel. From the strut to the float support, the angle was so much that the tube was bending and collapsing, preventing a good reading, so I added some 90 degree transition couplers at that point, and now the airspeed seems to be working well.
