I bought some thinner wall Gates mpi hose, its 8mm ID 14mm OD. This was more flexible and I was able to get a nice smooth run. I groomed the loom inboard a bit, so it runs up the side of the spine and doesnt end up in the same place as the fuel hose.
There is still a lot of "contact" between the airbox and pretty much everything in the vicinity, and as much as I hate doing it, just pushing the airbox down and tightnening it up allow things to go back together.
It doesn't help that someone managed to snap of BOTH side airbox rear bracker bolts, one side in the frame tab, one side in the airbox! I tried reverse drilling out the airbox one to no avail.
