I cut down a hose yesterday from a recent "junk" motor. The motor was low mileage and I am assuming the hose was too. I first looked to see about a restriction. Both hose ends were open fine to fit over the supply tubes, but the hose was almost crimped in the middle to restrict it down. It started about 1/4" and continued for about 1/2". It was identical to the one Pim pulled apart. It was not distorted, it is has a definite ridge formed where the line was crimped at a factory at some point. As I said in an earlier post, I am confident that an engineer at Honda or IHI decided they had to restrict the supply flow to the turbo.
