Detail of the No. 12 tube marking (a "fuel-down" tube)

Since the strap covers more than one tube, the line under the "120" presumably marks the precise location of the No. 120 tube.

I believe this marking is on the shiniest reinforcing strap, just below the ID plate between the gimbal outrigger arms, in dsc66981.jpg.
