Right wing tank would leak like crazy. Had my buddy reach out and straighten out the cap so that the vent hole was dead ahead, and it quit leaking. Seems as though if the vent is slightly to one side or the other, it creates a vacuum and sucks the fuel out. Just a thought.Larry----- Original Message -----From: [EMAIL PROTECTED]Sent: Thursday, September 11, 2003 3:08 PMSubject: [COUPERS-TECH] Re: Digest list: Ercoupe Technical Discussion (moderated)----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----
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
