The OEM fuel system is fine with stock injectors (assuming you have the updated fuel pressure regulator spring).

IMO the Air Dog is the better choice if you want to go with an aftermarket pump. They have made some improvements and their system seems to be very reliable now (not so in the past).

One other thing to consider too, is if you live in a cold climate area such as a sub freezing winter climate zone like I do, it's hard to beat a stock fuel system, especially the early 03' yr models like I have that have a heating element in the frame rail filter-pump, or as Ford calls it, the HFCM...Horizontal Fuel Conditioning Module.

My 03' has never gelled up, even in -20F
