I would be sure and check the vents on the wing tanks. If these were somehow clogged during painting or even by insects, this would cause the problem. The air needs to be able to escape or the fuel will not come back from the header tank into the wing tank like it is supposed to. It will pressure up and cause the fuel to overflow from the header tank. So be sure that both tank cap vents are free and clear. Jerry

Under no circumstances would you want to block the cap vent, even if it appears to solve the problem. With known history, it may be possible a bug or spider built a nest in the return line while it was apart perhaps? --- In [email protected], kim Blackseth <kimblacks...@...> wrote: > > Well, I thought it was fixed when we put the restrictor on the fuel > pump, but damn it, it's not.
