Some time ago I posted my experience with fuel spewing out of my left wing tank filler cap.
Since then, I have had further symptoms, which may point to the basic cause of the problem. My Coupe is serial 3034, which used the "intermediate new fuel system". This is shown in Figure 1 of Ercoupe Service Memorandum 43. On a recent flight, I started using fuel from my header tank. When I landed, the header tank was down by a couple of gallons. The right tank was dry, as expected. However, the left tank still had a considerable amount of fuel in it. IF my plane is plumbed as is should be, then the wing tank cross feed tube MUST be either crushed, or otherwise restricted. According to the diagram, the return from the header tank enters a T fitting on this line. Since the return flow doesn't seem to be restricted, this would probably eliminate the finger strainer in the tank itself. This would account for the spewing fuel, since the return on my plane goes into the left tank. If the cross feed tube were restricted, then the tanks would not equalize and I would have overflow. The tanks WILL equalize in time, so the tube must be present but restricted. I shall lift up the floor boards to see where the restriction is. Are the 53 year old tube fittings still available, or will I have to fashion all new fuel lines? Any input or opinions on this?
