vacuum.... boost....

[budderigs]

are there any changes that I need to make to the vacuum lines before installing a blower? check valves? what about the brake booster?

Check valves for the HVAC would be wise on most cars.

I'm pretty sure my Z had a valve for the booster as well.

Isn't there usually a checkvalve on the stock brake booster?
