Engine dress and hose clamps?

You're one of those hardcore "everything must look original" guys ain't ya?

Not at all. There is an area between real stuff and fake stuff that's no man's land.

In other words, go with real aircraft fittings and braided hoses or be ready for failure. That stuff you linked to is total junk. I would much rather have something that looks plain and WORKS than something that looks good and leaves you on the side of the road.
