Al: The first thing to check is to make sure that the fuel pump has the restrictor fitting installed in the out line. The out line is the one on the right side with the 45 degree fitting in it. The fitting is plugged, then drilled with a 1/16 inch hole to provide the approximately 7 gallons per minute fuel flow rate. If you do not have the restrictor installed, the pump over fills the header tank and causes the problem you describe. Also make sure that the vent in the cap is not plugged, and sits at lease 1/4 inch above the rubber grommet in the cowling. I have found the rubber grommet partially blocking the vent which will also cause the problem you describe. Also take the cap off the fuselage tank, and look inside to see if you can see the fuel return line. If it is right near the top of the tank under the cap, it may be too high. I had this problem on an early serial # Coupe. You can check the fuel return line to the left or right wing tank, by loosening the fitting at the elbow on the wing tank inside the fuselage, above the floor. Then gently blow into the line to see if the air comes out into the fuselage tank. If it is blocked, you would not be able to blow through it. Also, check the size of the vent holes in all three of the caps, if they are the vented caps. They must be the same size. If the vent hole in your fuselage tank is smaller than the hole in one or both wings, this can cause fuel to be forced out of the fuselage tank. I will be home this weekend, feel free to call me at 863 635 7916 if you have further questions.
