Hello folks, wondering if anyone can provide some photos or info on how the components circled in the attached photo. This is a 1983 GMC 2500, 350 "M" code engine (HD V8). It's a mess of vacuum hoses that don't go anywhere, so I'm trying to get some of the functionality working again, such as spark control for the distributor.
Not sure where the Thermal Vacuum Switch should be located (assume that it's controlled by coolant temp?), and which port on the Q-jet provides vacuum, best place to put the check valve and delay valve, etc.
