Fuel Filters? Loss of power...supercharger

[HummerMann]

GM lists FF864 as the only fuel filter for a 2003 and 2004 H2. It's the in tank unit and they don't list any other fuel filter at all. They don't even list one for 2005 on up. I was on the line with my Hummer dealership this morning ordering a lug nut and the parts guy said there is a special tool you can order from GM for changing the in tank filter more easily.
