Re: Air pump/vacuum issues.
I wouldn't concern myself with the air pump if the engine runs good and you have no testing. As long a manifold ports are plugged, you will be ok. You can take the bracket off if it doesn't effect any other mountings.
Be sure to keep your PCV valve installed. You need vacuum to the dash controls (not 100% sure on your year). Later model 4X4s need vacuum to engage 4wd mode, again not sure on your application.
Good Luck, James
