NG8264723, I'll do a shameless plug for Ford/Motorcraft parts. The Ford pn# is E4ZZ-9278-A and the Motorcraft is SW-1547-B. Motorcraft is readily available at part stores such as O'Reilly's if you don't want to go near a Ford dealer. You don't necessarily have to buy the Ford item, but just make sure you purchase a top line quality part. My experience with the cheaper units was a lot of leaks and erratic gauge readings.
