There are various reasons why you might want an upgraded fuel pump for your 04-07 Super Duty. First and foremost is the age of your current fuel pump - if you're still running the factory component, you could already be in dire need of a new fuel pump. Another reason is to accommodate a modified engine with more power and thus a higher demand for fuel. All of our aftermarket fuel pumps come from reputable manufacturers with great warranties so you can shop with confidence. Also be sure to check out our 04-07 Cold Air Intakes section for even more power and efficiency!
