Jim, The exact configuration of the fuel system depends, usually, on the serial number. There were some changes made as production went along. And, then, sometimes when maintenance or restoration is done, some change could occur.
Please post your plane's serial number to help the experts. The crossfeed between tanks should always let them be pretty nearly equalized but a small difference is possible. Even a mild slope to the ground could account for a 2" difference. Be sure you keep an eye on this for now. On rare occasions, we've heard of planes with crossfeed problems. Hang on and the experts should chime in, soon. Ed
