Here are two photos I just took. I may be crazy, but I really think this one looks different from the original part. I also got a photo of what I assume is a part # (it's on the top, back of the part - by the firewall).

If the picture is what was replaced, they gave you an entirely new fuel head, not just the WIF. By the way, the WIF is simply a function of the spin-on filter. The most likely source of air infiltration is a degraded component in the head (plastic puck or heater plug, at stated previously). Glad to hear it's better for you. It should perform like new for you, now.
