For those that don't know... the owner of BFT, formerly known as DFA, who makes and sells the Vegistroke, has designed his own new pump to replace the FASS units previously used on the V3 manifold. The new pump eliminates the famous "tower bolts" found on the old FASS units, and simply bolts to the manifold without the backing plate. This new pump also uses tighter tolerances, and I'm told is whisper quiet. This is a direct swap/plug in. This is the new and improved Scorpion pump...
