Either that or the clunk line has a pin hole or came off in the tank.
That shouldn't have an effect until down to 3/4 tank or so unless the end of the line is floating high in the tank. I got the feeling that this was at near full tank levels.
It will if you raise the nose up.
He sais he was lowering the tail while on the ground or tilting the nose up, NOT that he was picking the plane up and pointing it at the Sun. I was answering to the conditions HE was going through in which case I was correct.
I have a number of tanks that have the stopper near the top of the tank and just tilting the airplane on its tail will bring the stopper out of the fuel in a full tank (knowing that a full tank does not mean that there is no air at all left in it) But not knowing the style tank used in the F22 PTS I will concede the point.
I would suggest however a complete inspection of the tank and all the fuel lines.Never count an any manufacturer to get it all right and sadly alot don't.
