The fire pump is located in the electrical service room. In NYC, does the fire pump circuit have to be 2 hour rated if located in the electrical service room?

Am i interpreting it correctly? See exceptions in sections 695.6(a) and (b) in the amendments
https://www1.nyc.gov/assets/buildings/pdf/ll39of2011_electrical_code.pdf

Whats the difference between supply conductors and circuit conductors?

I believe the short answer is "no". Look at the 695.6(A) and 695.6(B)(1) exceptions.

Not really. There are a lot of recommendations in the Appendix notes, but like FPN's in the NEC, they are not part of the code.

Does 4.12.1.1.4 tell us we can't have a fire pump in the electrical room if the electrical room contains equipment not associated with the fire pump?

IMO, You can't have the electrical equipment in the fire pump room if the electrical equipment supplies things not essential to the operation of the fire pump.

From 2019 NFPA 20:

4.14.1.1.5* Except as permitted in 4.14.1.1.6, rooms contain‐
ing fire pumps shall be free from storage, equipment, and
penetrations not essential to the operation of the pump and
related components.

4.14.1.1.6* Equipment related to domestic water distribution
shall be permitted to be located within the same room as the
fire pump equipment.

I was looking at the 2013 edition, but the wording is exactly the same. Unless all the electrical equipment is related to the fire pump, jockey pump, and/or controller and any other auxiliary equipment specifically related to same, the fire pump shouldn't be in the electrical room.

The fire pump I witnessed is existing in the electrical room with apartment meters and other unnecessary circuits, can that remain or must it be moved?

That's a question for the AHJ, and it's going to depend on what, if any, code was in effect when the building was constructed or the fire pump was installed. It's probably going to be easier to move the electrical equipment than the fire pump, depending on the relative sizes. If this is in NYC, I don't see how it was done without the DOB and FDNY buying into the arrangement. Assuming permits were pulled.

By the way, to answer your original question, the conductors located in the fire pump room feeding the fire pump do not have to be 2-hour rated. Assuming all the other requirements for the room have been adhered to. However, if you're running something like VitaLink, you might as well just continue with that inside the room.
