The decimal equivalent seems to be correct, (1/16") The pump should provide approx 7 GPH. I would suspect a restriction in the overflow from the header to wing tank, or a restriction in the vent on the wing tank filler cap.

Bill ---------------------------------------------------------------------------- To: [email protected] CC: From: [EMAIL PROTECTED] Date: Fri, 26 Oct 2007 04:42:06 +0000 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.
