Firestone 9284 Air Compressor

I believe i need to replace my pump. the part number is wr1-760-9284, is this the exact same one or will it work in its place? just want to verify!

I’ll need to replace my air compressor, i use it in a ford 450 diesel. the part number is wr1-760-2186, will it work in its place?

Hell of a description. Does it work on bags? Is it automatic? Does it come with controller?

Is this compatible for a 3.5 motor on a 2008 nissan altima?
