I suspect that my car has a vacuum leak somewhere. All of the vacuum lines are pretty old and brittle, so I am thinking about replacing them. I don't want to use the colored silicone hose, but just a rubber replacement. Are there any places that sell OEM style hose in bulk lengths to save some cash?

 

Just about all parts stores sell them by the foot -just take a small peice in so they can compair it for you.
Normally, it is not as nice looking as OE, but works.

 

StylinMotors.com has some nice lines. They carry black, but they're 'shiny' so I don't know if that is what you want. I typically just run up to AutoZone and get it by the foot.
