Hey guys just installed new head studs and C grade head gaskets and did ppe dual fuelers also put on both new and bigger PPE cp3 inlet fitting on both cp3s and i now have some black smoke at idle.. PPE says it must be my fass 150 putting out to much pressure but of course it never did with a single cp3 but they claim its cause of the dual cp3 kit. Fass says they have internal regulators and that it shouldnt have nothing to do with their pump.. What u guys think?? thanks

Ok i figured it out i had a return line bent from the new cp3 and wasnt allowing the unused fuel to return to the tank... thanks
