Vacuum Lines
Hey guys, having some trouble figuring out where all the vacuum lines go. I have tried seach and have not found anything detailed enough to help me. I especially need the routes of the evap canister. I saw the underhood sticker picture but it is not helping. The car is a 89 L98 car with cruise. All help would be great since this is my first TPI car and I got it with out the engine installed or anything labeled.
Thanks a bunch
Mike

There should also be a vac line from the rear of engine that supplies vac to the cruise and to the vac reservoir.This line tees off from the one way valve shown which also puts vac inside for the A/c controls.If the reservoir and one way valve are not hooked up your A/c controls will drop out every time the engine vac changes like when you accel
