Greg, Sounds like 'Tygon' tubing sold by Aircraft Spruce specifically for airspeed pitot and static lines. I recently replaced auto type heater hoses in my Coupe with this type of hose for the vacuum instruments and it has worked well so far. With approx. 50 hours of flying since installing the new hoses I've seen no difference in instrument readings. On the plus side, the heater hose and brass fittings I replaced were much heavier than the plastic hose
and nylon fittings. I can't believe this thing went through at least two annuals with the non-approved automotive hoses and was signed off.
