Where to buy fuel filters separately

[Gmoney69]

Okay so iv got the h&s fuel filter conversion and only need to purchase the main filter on the bottom rail for the fuel water separator. I could have sworn I saved a website where you could but I can't find it anymore. The wix filters for the conversion are all over. Any one know ? Thanks !
