what that adapter kit does is it makes the -6AN fittings that come on the SFMU into a female 1/4 npt thread which you can thread the -4AN fitting on. you can use the -6AN fittings to hose barb couplers. i say do not waste your money on the adapter kit from vortech. just go buy 2 of the -6an to 3/8inch hose barb fittings from your local speed shop.
