Hi all: I got in 2.4 more hours of shakedown flying after the big rebuild, and experienced one unsettling anomaly: I had the wing tanks filled at the local FBO, and he filled them right to the top. (As a matter of fact, the yokel that was pumping that day over filled, and poured a pint or so over the top on the right wing.) Well, after taxiing to the runup area, and then proceeding through the runup, I noticed that the header tank bobber was maxed all the way to the top of the tube, considerable fuel was exiting from the cap/vent area. Needless to say, I wasn't going to fly like that. I shut her down and scratched my head a bit. What I surmised was that since the taks were really over full, fuel couldn't drain back to the wing tanks adequately. So, I removed 1 gallon from the left tank, then ran it for a while at idle, then a while longer at 1700. All seemed to be back in order, and we took off for a local flight. Next, during am 80mph climbout to 4500', the left tank vented quite a bit of fuel, although the header tank bobber was good. As soon as I went level, or descended, the left tank would stop venting. We returned to our home field and did a couple rounds in the pattern to burn off some more fuel close to home. Lastly, I flew another 1.4 hours in the afternoon without tanking again, and didn't vent any fuel at all anywhere. Finally, my question: Does this typicaly happen with ercoupes? Should I always be carefull to stop a bit short of full when tanking? Or, is it possible that the return line is not flowing adequately? Any advice will be greatly appreciated!
