Good stuff so far Igor. And if that yellow hose is the one I think you mean, it's the main fuel feed hose. It has a central clear section, so that fuel flow can be monitored visually.
I got most of her painted during the weekend, about the only part that is painted on this Bf-109G-6 is the yellow cowl other than that, waiting on some things to dry, I'll definitely complete her, but aye the time ran out on her, no worries she'll get done when she gets done :S
