Need diagram of vacuum system for 1988 jeep comanche pick-up 6 cy

The vacuum system in my 1988 jeep comanche was disconnected by my step son & we are unable to put everything back where it belongs without a diagram to use. The motor isn't working properly now due to the situation. It speeds up & almost stalls now & has a loud whistle as one of the hookup spots doesn't have a hose on it & if you plug it, it stalls the engine out. I need a chart or diagram to see where to rehook the lines up properly.

Haynes manual has a diagram. Main important hookups are to power brake booster, fuel pressure regulator and map sensor. also need a connection to a/c controls inside drivers compartment and evap system canister. will also need connection to egr valve solenoid if you have one. as well as pcv on valve cover (or ccv which replaces pcv on some)

My son bought a 1988 Jeep Comanche 2.5l 4 Cylinder. Ran great for a few days then stopped. Turn over & fire but not getting any fuel. Seems no power to fuel pump. Could it be caused by the solenoid that...
Check fuel pump for power...Check fuel pump relay in power distribution center (they often have same # relay used in several applications, You can borrow one from a non-essential system and just swap it to do a quick check.) Also, I would change the fuel filter. If plugged, the pump may be shutting down early (and it's a good maintenance item even if it has no effect on problem.)
