Not satisfied yet, I upgraded from p4070 crankcase, firstly the bolts were missing, there was a hole in the little bag, the fitting they supply, is 3/8 which is fine but the barbed side is for 1/2 hose so be prepared to get fittings, the ground wire is so small and long I doubt it's even a proper ground offers, probably the reason these pumps aren't working won't last long, hopefully this thing will pump in anticipation of adjustment
