I got quoted a ridiculous price when it wasn't obsolete about 10 years ago. It turns out that what you are getting is an "assembly" which includes the nylon tubing and the various endfittings. Still a ripoff. That's why I got mine from McMaster Carr with some adapters to step up to the rubber fitting. Since then, I've seen the part at a local Napa and I think Pep Boys in one of those blister packs that says Help! on it or something like that. They usually have oddball parts like that. You might not find your exact part, but you should be able to find something you can adapt. Power brake systems use them in the vacuum booster line, but the size may be too big.
