Pass side port-To EGr solenoid
Large port in center-PCV Valve
Medium port under large port-EVAP cannister
And, if there is another small port on the drivers side of the throttle body, that usually goes to an air pump diverter valve if you have it....if not, plug it off.

Ignore this - you are TBI. I'll leave it up for reference

Vacuum hose routing - 1987-88 Federal (VIN K) 5.7L engines with automatic transmissions (G10, 20 and 30 models)

You must be registered for see images attach



Note: Covers all K VIN's except not with heavy duty emissions - and not California

Thank you for this but wherever I look online and all threads I can not seem to find UFL. Any idea where I could? Thanks
