Truck Repair: fuel press. specs, engine pumps, pt type

Question
What are the fuel press. specs. on a 1987 CUMM. Big Cam with STC injection and a PT (TYPE G)      AFC VS fuel pump  

Answer
What kind of specs you need?If you want the actual fuel pressure I would need to know the fuel pump code.It is a 4 digit number on a metal tag on top of the pump.It will be hard to check those old engines because of the govenor controls the pressure the whole RPM range where as the new electronic engine pumps just put out around 150 PSI all the time.Let me know what specs you need.
