I have 92 s10 blazer 4x4 v6 4.3. Where can I find a diagram of the vacuum hose. I have feeling there is a leak some where.

armed with a vacuum guage check for 18 inches of vac...use some plastic adapters. with the guage in line with the lines you should be able to do this with no diagrams,,,,the only reason a diagram is required is if the lines/componets have been improperly routed..

I would expect you to find many leaks if this has never been done as these lines go bad at the 10yr point...start at the engine , this is where the heat does the fastest damage ...then around the hvac venting controls ..

Search my posts for vacuum leak, for detection procedure.

It is perfect leak test.
