Chuck, you could also slide a rubber hose over the overflow outlet in
the header tank and blow through it. You should not feel any
restriction to flow.

Chuck,
It sounds to me like your overflow line from the header tank back to
the wing tanks is either plugged or partially plugged. The fuel level
in the header tank should never reach the top of the header tank,
because the overflow in the header tank is set at a level lower than
that. This isn't a problem with the filler cap gasket or the fuel
pump, especially if you didn't have the problem before. A clogged
overflow line or some trash blocking the overflow outlet in the header
tank would cause this problem. I would start by looking in the tank
with a mirror and flashlight to see how the overflow fitting looks.
Let us know what you find!

Subject: [ercoupe-tech] Overfilling header tank
I fly an early 415-C (s/n 287) with the early fuel system plumbing.
On a recent flight I smelled fuel in the cockpit (big red flag).
After removing the header tank and checking for leaks, inspecting all
screens, and fuel lines/connectors etc; and measuring the fuel pump
restrictor (0.063) - all clean- my A&P and I are at a loss for
causes. A recent test flight revealled a slight leak around the
header tank filler cap, and the float gauge was at the top of the
sight tube- and over fill condition. Any ideas for the next step?
Replace filler cap gasket? Replace restrictor in fuel pump? Carefully
monitor RPM (I have a 7146 extreme climb prop at my field elevation of
4160')? What rate does the fuel pump transfer fuel to the header
tank? This condition had a rapid onset.
