DITTO For sure...There is no way the tanks and cabin are making contact. The crossover line does not appear to be stabilized and could be moving around. I would bet It is caused be mishandling of the cabin during installation. Stabilize the line and fly it. If there had been pylon whirl, blade shake or any other major issue, these scratches would be the very least of the damage.
