Hi All: I need some advice; I just went to an airpot 15 min (20 miles) from my base and filled the wing tanks to within a 1/2 inch of the top. The header tank waS ABOUT 3/4 FULL. ON TAKEOFF I NOTICED FUEL BEING SYFONED FROM THE LEFT TANK FROM UNDER THE CAP , After landing back at mt airport I measured the fuel level and it appears that I lost about 3 gal of fuel. I checked the pin hole cap vent and ther both open. This plane does not have a mechanical pump. only a electric pump located on the firewall and was placed in the system where the mechanical pump was and worksw fine. It was done legally with all paperwork by previous owner. I first noticed this problem last Sunday on a 3 hr flight after refueling with the fuel pump pumping. It stopped leaking after about 2-3 minutes when I turned the pump off and burned off some fuel. After this refueling I appears to continue with or without the pump on. This is not only costly with the price of fuel but could be deadly. . There are new gaskets on the caps but the leaking cap is not quite as tight as the right one that requires a pair of pliers to remove. Do you thing switching sides with the caps to see if the cap is the problem, is a good idea Any advice would be aprecated ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
