You may contact a GM dealer for assitance in getting a manual for that year and model.
I would also recommend getting a good repair manual for that vehicle. The savings for one repair will more than offset the price of the repair book. I use manuals produced by Haynes which can be found in most auto supply stores like Advanced Automotive or Auto Zone.

When you flush your radiator, the heater core gets flushed as well. You will have to run the vehicle untill the heater is blowing hot air during the flush, that way its going through the thermostat. Empty the radiator as per normal and thats it.

EGR valve sticking or bad vacuum leak, might be a place to start. I presume the ECM, control module are functioning properly?

It is rather complex but it can be done at home. It will also require special tools. The haynes manuals do cover this repair I believe.

Very much so. The pressure regulator is designed to handle the OEM pressure.
But, I'm confused with your story.
A 1987 F150 with a 5.8 engine should have a carb, not fuel injection.
The 6 cyl and 5.0 engines do use fuel injection.
And, I only show inline fuel pumps for the fuel injected models in O'Reilly's book having 70-95psi. Nothing listed that would have 45psi.
Are you sure about your numbers ?

For you to switch this vehicle from 4 wheel to 2 wheel or 2 to 4. You should follow these steps. TURN VEHICLE ON, PUSH ON BRAKE PUT VEHICLE IN NEUTRAL.STILL HOLDING BRAKE AND VEHICLE IN NEUTRAL PUT VEHICLE IN 4 wheel or 2 wheel if desired. IT SHOULD WORK. Good Luck
