If your original Wet End has a Bleeder Barb and the heads of the Bleeder Screws in your old wet end have a spot for a flat screw driver you will need a new bleeder barb... If the original has a wing nut style you already have the newer style bleeder barb and will only need a new one if your original one breaks..
