Just keep an eye on the plastic hose, they tend to leak. I ran the upgraded copper line in my Eclipse, but it was a PITA to run, and probably could still fail from vibration if I didn't have solid mounts.
The grease gun hose is a neat idea, didn't think of that. I do know they are a little stiffer than SS hose, so you might have to watch the belts and frame over there.
