That's a Perry pump under the pipe. It works, just need to find a better place to mount it. I've tried it up on the shock tower, but you need to get it as close to the crankcase as possible. Too long of a line from there, will lessen the strokes of the pump, as the line tends to absorb much of the pulses. I'll get it ironed out. But it does help the performance, at least on my truck.
