Thanks for the quick reply, Larry. That clarifies things for me! I'll be extra careful when fueling the mains!

I''ve flow my Ercoupe 1600+ hours in 15 years and I believe I have added fuel to the cowl tank twice. That should be your reserve, and never go into it. Even if you do burn some fuel in it, take a few short flights and let the fuel pump refill it. There are lots of small pipes moving fuel around your system, It's quite easy to overwhelm them with fuel gushing from a filler hose!

Have not flown the coupe long enough yet to see the header tank even begin to draw down. Only have put fuel in the mains. I try to keep about 15 total gallons in case someone wants a ride. Different and new drill for me regarding fuel as I always topped the tanks after flying my Bonanza. Even after flights of less than an hour.

Fill header tank last so you can over fill wing tanks with the return line... just being a butt-head... Do let the hearer tank drain before filling wing tanks. the return line will drain/ flow back to to the mains if the header is to full...

Fuel overflow problem was created by John Farrell
I have a possible cause of my fuel overflow problem and fuel leaks:   I may have filled the left tank too fast under estimating the amount of fuel in the tank.  Filling too fast may have created an air bubble which caused the fuel to "bubble" out of the tank and because of the wing's dihedral the fuel migrated toward the wing fairing and down to the fuselage ending up as a leak down the lower left panel below the fuel primer.  When I taxied back to my hangar and again opened the fuel cap more fuel "bubbled" out.  I opened the sump drain for several minutes until the fuel level went below the top of the tank and the dripping stopped.  

I flew the plane the next day for about 45 minutes burning about 3.25 gallons.  No leaks, drips anywhere.  Comments/suggestions ??
