Yury,

I think the AD you refer to in post #19 is superseded by the two xfeed valve installation.

Switching off one CWT pump almost guarantees an imbalance on the B767. As I recall it, the left pump feeds the left engine and the right pump the right engine. Each CWT pump only runs when its engine is above 50% N1.
