Question about 1986 Chevrolet K3500
Son had to replace heads on '86 Chevy Blazer K5, 5.7 liter V8. Can't figure out how the hoses go back on. Is is possible to get a vacuum diagram for this vehicle?

SOURCE: Need vacuum diagram
I can't send you a diagram but I can tell you the basics that should get you mobile. Take a vacuum line from the lower front of your carb and hook it to your distributer vacuum advance. Take another from the front of your carb and run it to your EGR valve. It should be beside the carb on the intake manifold. At the rear of your carburator there is a large line coming out. It should be steel. It provides vacuum boost to your power brakes. Hook it up. Make sure all other vacuum outlets on the carb and intake are blocked off and you should be able to get mobile.
