I just switched over to a vacuum set up off a 85 regal. When I started the car after switching over I could hear a(hissing) vacuum sound coming from under the dash and the car is idling bad now. I assume that the a seal on back of the booster is leaking. Can I buy a replacement seal or do I have to get a whole booster?? Can't seem to find anything on autozone or oreilly's web sight for just the seal.
Thanks,Tyson
