Geez, got back from Yosemite and watched the wind blow for 2 days. This morning bloomed bright, cool and calm. Time to fly. Got to the field and started fueling the bipe. Fuel started poring out the bottom. Take the plane apart and find another split tank. A new Pylon brand tank split at the stopper and I hadn't even started the engine. I guess I could have tightened the screw to much but it's never happened to me before. I think Murphy is on the side of this plane. Thankfully I fuel proofed the inside of the plane including the radio compartment. Maybe tomorrow. YOU ARE GOING TO FLY SUCKER, MURPHY or NO MURPHY.
