OK, I misunderstood your original post. I did more picture looking than reading for comprehension and thought the issue was the unsecured fuel line being cut by that shield. You’re saying it was more likely flexion or stress from the line now being unsecured in that area where it was attached to the OEM fuel tank skid before it was removed.
Gonna check mine again. I’ve actually checked it before to make sure it hadn’t moved and started to rub on something knowing that the support at the rear was off. I never thought about the flex being much of an issue, but I think I’ll find a way to re-secure it.
