I have a 2003 expedition. The pump is around $300 for a pump and sender assy. Can I just purchase the pump itself and reuse the sender? I can't find a part number for the pump itself. There's a bunch of aftermarket companies selling them but they fit 97-03 model, and I think that's completely different than my 2003. A bunch of aftermarket companies have the year wrong on the expedition, it should be 97-02.
