I bought a "slightly used" kit off Ebay for my 04, and it did not come with a fuel pump? Should it have? Do I need a bigger one? If so, is it the same as the mustang pumps?? The instructions do not mention needing/installing one???

 

I'm not sure of any aftermarket supercharger that comes with a larger fuel pump. I don't think you will need one, unless you plan on using a canned tune from Powerdyne and they have that factored into their tune. If you are custom tuning, and plan to keep the power below 450 hp at the wheels, your stock pump should do fine.
