As part of installing an EFIS into my RV-6A (and keeping original ASI), I am replacing all the pitot & static lines behind the panel.
I'm using Tygon tubing for it, and the Tygon didn't fit well over the AN fitting on the back of the ASI, so I unscrewed it to replace it with a poly barbed fitting. I was surprised to find a spring inside the fitting.
I don't see anything inside the ASI inlet that the spring would be operating against.
Does anyone know what this might be for? Is it required for something, or can I just replace it with my poly barbed fitting & get on with the install?

thanks for any help,
