This thread is almost at it's end, but I might add my two cents worth of observations. Please notice that the Ercoupes originally were fitted with basic VFR instruments only. That makes one Airspeed meter and an Altimeter if I am not wrong. I found that ERCO installed one aluminum pressure tube and a similar tube for the static pressure through the wing, ending behind the dash, directly into the Airspeed meter ports. The static line has a T-piece that would allow to attach another short piece of tubing to the altimeter. On my Coupe the tubing from this T-piece on is completely plastic tubing. The advantages of the plastic tubing shows especially when working behind the panel. It is much easier to install instruments. No stiff lines to worry about that could chafe or touch electrical wires. I can only recommend the use of plastic tubing behind the panel. As for the initial lines that feed through the wing, I'd stay with them. It is an approved and proven system. Hartmut
