How long would you expect petrol fuel tubing to last in a model. The fuel tube in my DC3 is genuine Tygon tube. Although my model is now in it's fourth season, it has had no more than 50 flights to date. I've inspected the fuel lines and they are no longer bright yellow, but are what I would call a very pale brown, they still feel soft and flexible to the touch. I store the centre section standing on it's leading edge so the felt clunks are always stored out of any residual fuel in the tank.
