Just as a follow up to all ... The over-flow of our header tank was due to cork debris from our cork fuel gauge. About 5 match head sized particles had deteriorated from our cork and would eventually wedge themselves between the top of the fuel tank and the over-flow return tube. It didn't completely stop the fuel return to the wing tanks, but it restricted the flow enough to cause the overflowing of our header tank. Many thanks to all that offer assistance! And a special thanks to my buddy Hartmut for all of his trouble-shooting efforts Richard

To: "TECH-FORUM" <[email protected]> Cc: [EMAIL PROTECTED] Date: Thursday, July 3, 2008, 10:23 AM Hello all, after completing the Paint/Polish scheme on our Coupe, I took it for a test flight last Friday evening. The plane looked great and flew perfectly. My partner took it for a flight yesterday and advised that when he reduced power on final approach, fuel began to over-flow rapidly from the header tank. As he would add power to the throttle, the over-flow was reduced but not stopped. As you reduce throttle power, the over-flow increases a great deal. I attempted to take it for a test flight this morning to observe the over-flow issue myself. As I was taxiing, I noticed the header tank filling by watching the float indicator go higher than usual. It then began a pretty heavy over-flow to where fuel was running down the cowling. At that point I just chopped power to avoid a fire. Now as it sits in my hangar, the fuel float is back to where it should be. It's acting as though the fuel return back to the wing tanks has slowed. It appears that the fuel pump is sending fuel to the header tank faster than it's returning to the wing tanks. Does this sound like a partial clog in the header tanks return lines, or could something else be causing this issue? I did check the vents on all 3 fuel caps, and they are clear. Other than that. I'm at a loss. Any advice will be appreciated. Thanks, Richard
