I need to make up a new vacuum tree, and the only hoses I have that are the correct size are fuel line hoses.

So, can I use fuel line hose as vacuum lines? I would assume yes, no problem, but it's one of those things that I may be completely wrong about.

Thanks everyone!

should be able to with out a prob. as long as they are the same or you can go get some hose from an auto store

That's actually what brings me to ask the question. My local Pep Boys didn't have the size I needed in stock, (in vacuum line), but they did in fuel line.

Thanks. :)
