If your sucking the plunger down,correct me if im wrong but would that mean that either there is a blockage before the filter or could the lines be hooked up backwards and its sucking from the return line making the plunger sink? I know this is far out there but wtf never heard of that.maybe the rubber hoses going to the cp3 are mixed up???

Wow thats b.s. check for a collapsed line below where the quick couplers are next to the brake booseter and below i guess there is a problem with those lines breaking down inside and from the suction it collapses the lines....just something to check before you go to the tank,if you have someone strat the truck just watch and see it that line goes flat,also back by the fuel cooler
