Shouldn't be a problem, Nathan.  To me, it would be just like
replacing your factory water hoses with top-quality Gates hoses or
your factory oil filter with a Fram.  Vacuum hoses are expendable
parts, just like water hoses and oil filters, and can be replaced by
aftermarket parts...just as long as they don't create a "performance
advantage."  You can even replace clutch and brake hydraulic lines
with solid metal or metal braided lines as long as the car is earlier
than, I believe, 1992.
