From Genos:"The Schrader adapter is used on 00-02 trucks where the Schrader valve is located on the side of the VP-44 injection pump. " Now that I look closer at this thread the original post is about a 99, so that wouldn't work any way. How ever I would like to know your suggestion for my 02? Would this be a good option for me, or go with the T style fitting as others suggest. I have been told FASS will replace every thing up to my VP by some, and others tell me I have to run it through my stock fuel filter?????
