Hi All,
As a follow-up, I went to the hangar this morning to determine the proper size for the 'grasshopper' nuts required to secure my ASI. Only the two right side screws were in place, so the instrument was loose in the panel. Anyway, the correct size is 0.375", so I've added those to a Spruce order!
OK, now I'm not saying the previous owner was half-a$$ed, but I found that the clear plastic tubing from the pitot tube was connected to the ASI with a combination of electrical tape and a ty-wrap.... The ASI has a short piece of copper tubing connected to the input port with an approximately 0.18" OD. The clear plastic tubing has an approximately 0.25" ID, so the copper tube was wrapped with tape to expand the diameter, and the tubing was then held in place with a ty-wrap...... So, what are the proper fittings to make this connection??
