Reverso 360014 Impeller 38-2314 Chemical Resistant OP-4/0P-6 Oil/Diesel Pump

I ordered 2 of these for my Reverso 3 station oil changing system. on my yacht. the first one had over molding that needs trimming away. I see QQ is not to the usual standards at Reverso. The second one was fine and did the job but unfortunately exposed a cracked manifold on my system. I will machine the manifold out of aluminum so I never have to worry about it cracking again. otherwise impeller does as it should.
