Chevrolet Repair: 1987 Chev vacuum lines diagram, vacuum lines, neighborhood library

Question
I need a diagram for a 1987 Chev 450 or 454 Encounter RV vacuum lines please?

Answer
Hi Linda,

You need to get ahold of a Chilton book that has those diagrams in the back.  I don't have that diagram in my large library of repair manuals.  

You can usually get these books at the neighborhood library.  However, the trouble is RV.  I believe that diagram is the same as, or similar to, a heavy duty pick-up truck.  You can try to find that manual if the RV one is not available.  You can also try the RV dealer in your area.  Or try Amazon.com for a manual.

Good luck.  Sorry I couldn't help more.
