No, I meant the opposite. With all three tanks full sitting on the groung with in minutes of fueling the fuselage tank will drain into the wing tanks over flowing the wing tanks and will drain the fuselage tank down until it shows about one inch from empty on the fuselage gage. Dan Wow. That is weird. I have never heard about such behavior. I can only explain it with the fact that the line that builds the overflow in the header tank is broken off right there where it is passed through in the tank, thus making the overflow almost on the bottom of the header tank. You might be able to look into the headre tank and see something, you should see a pipe biulding the overflow line. Maybe someone more experienced of the group can help out here.

Dan >>> "Hartmut Beil" <[EMAIL PROTECTED]> 05/17/05 08:02AM >>> Dan. When refueling, don't fill the wing tanks to the neck. I usually leave an inch or so room for the overflow from the header tank. The header tank I never fill, since it is filled to it's "neck" by the fuel pump. The neck is defined by the overflow line and should be an inch or maybe more below the real neck. I think that explains what you meant with "there is about an inch showing on the fuselage gage."

With both valves open and wing tanks full, fuel will flow back into the wing tanks causing them to overflow. This happens until there is about an inch showing on the fuselage gage.

Check whether you or the mechanic closed the fuel valve that disconnects the main tanks from the pump. It is on the right side under the header tank/dashboard at the fuselage a few inches before the fuel line passes trough the firewall. Lever in line with the fuel line would indicate the valve open. With the valve closed, no fuel can be pumped to the header tank.

Shortly after getting her home I found that when I filled the fuselage tank it would drain from there into the wing tanks over flowing them. When I was flying home the engine pump would keep the fuselage tank full, not now. (fuel pump ?) Anyone ever have this happen?
