Yes, your assumption is correct. Thanks for the number.
You need a long zip tie or put two together. I put it right behind and below the secondary. There is an aluminum frame reimforcement piece (non technical term) that runs along the path of the oil line ( In fact, the oil line is already zip tied to it but through a drilled hole). I slid a long zip tie behind the reinforcement piece and then around it. This allowed the oil line to be pulled tight against the reinforcement piece. Once you take off your secondary I think you will see what I'm trying to describe. If not, let me know and I'll send you a picture.
