You'd be suprised how much harder the pump has to work due to the filter being clogged.
Where do you buy the filter?

I remember seeing pics of a factory pump where the hose from the pump to the fitting got a pinhole in it and and created lean issues. I've noticed that my vacuum gauge goes down 1 mm/hg when I get to a 1/4 of a tank also, and the truck isn't as peppy....or wasn't as peppy lol.

WTF! my damn filter is on the inside of the tank and is apart of the fuel pump... Yours is a return style that has an external filter mine is internal and is not replaceable...
