I am not sure how that type of tubing will hold up. As you mentioned it will be exposed to more heat and will have pressure applied to it.
There should be no dripping in the blige coming from the new dripless shaft system.

I'll definitely look into it when I get on the water. I think it was a little dirty when it went in but mostly the dealer not cleaning up after themselves.
I just changed my 08 lsv dripless feed from the factory designed hot water supply on the exhaust manifold to a cool water supply, like others have shown it done on newer models.
My oil cooler also has a drain on the bottom (like most do, I'm sure), so I plumbed the line to that. I could not find the exact barbed fitting that I needed in the little town I live in, but I did find that a npt air valve fitting fits perfectly. I removed the valve insert to allow the water to flow freely. The nice thing about the npt air valve is that it is small, so it allows the supply line to clear the alternator, which might not have worked with the normal barbed fitting I had in mind for the job.
I had to crank down on the hose clamp to ensure that the supply line would seal well on the short npt valve, but it worked out fine.
Once I had the correct parts, the job itself took all of 15 mins or so.
Hmm, this thread has me thinking about doing what you just talked about Highrider. Might not be a bad move to change the location of the water pickup from where it's located now (factory location).
I don't have any issues currently with leaking or anything, so I'm not sure if I should mess with it... but I do like the idea of cool water running in the dripless seal versus hot manifold water.
I didn't take any photos but I can the next time I pull the cover off. Maybe this weekend?
