Hey Kim: The first thing I would check is to make sure the fitting on the out line of the pump has a restrictor installed. This is the fitting (generally on the rear of the pump) which is highest on the pump body. It should have a 45 degree fitting installed that has a restriction installed with a 1/16" hole drilled in it. This allows about 7 gallons per hour of fuel to be pumped from the wings to the header tank. If a fitting has been installed which does not have the restrictor, then too much fuel will be pumped into the header tank (more than the overflow line can handle).

All... We test flew my newly re-built 415C today and all appeared well, but one detail and I'm looking for some advice... The header tank was overflowing, as it appears the pump was filling the header tank, but the overflow back to the wing tanks was not working... What did I do wrong or what should I check??
