You definitely want the pump in the ignition circuit. If you have a crash you (or a responder) wants to be able to isolate the pump with the key, not having it merrily pumping away on its own circuit.
I have put a separate switch in series with this though as a theft deterrent. It still gets its power from the ignition key though.
