vacuum hose for brake boost?

I know this may sound simple, but I can't find any 3/8" ID vacuum hose for the brake boost.

Mine is split so I went to the auto parts store and all they had was 3/8 fuel line. I bought some and used it, so my brakes and turbo now work, but when I got home I noticed that the vacuum is so great is collapsed the hose.

I pulled the hose off, release the vacuum and it became a hose again, instead of a ribbon

The hose I took off originally was very stiff, and plastic. Almost like a PVC or black poly pipe.

Anyone know where I can get some?

thanks,
dave

You don't replace the hose, you replace the part. I highly recommend it.
