This before and after (shortening the tank) shot shows why the tank had to be shortened.  It was very close to the end of the tail shaft of the transfer case before shortening about 10 to 12 inches.  Fuel capacity loss is estimated to be just over one-gallon.

This photo is a companion to Picture 4.
