So you put the water separator between the factory filter and the HPFP? Seems pretty simple. Would there be any benefit to having the water separator before the factory fuel filter? That would keep water and some contamination out of the factory filter, extending it's life, right? Not sure if there's a good place for it anywhere, just a thought.
