No way is that a genuine Cummins lift pump. I sell hundreds of them a year & everyone comes in a blue plastic bag & also has the weep hole & also the part # & ser# etched into the mounting flange on the same side as the weep hole. Also on opposite side of pump, main part of the body it says "Cummins ABFJV - Made in China”....the 4988747 pumps are the updated bigger piston pump at 30mm vs the older 26mm #3936316 pumps. On a modified engine, you can fuel the difference in fuel flow. The picture further above in thread looks to be a genuine one.
