I haven’t been on here in ages but thought I would chime in. You are correct, genuine Cummins ones are now made in China. I buy a lot of the lift pumps from Cummins direct and they do say “Cummins ABFJV - Made in China” now. They stopped buying from Carter awhile back. Haven’t had any of the new Cummins, made in china ones come back, with hundreds in the field well over year now, so I would say they are fine. The other bonus is if you buy the genuine Cummins 4988747 they are 30mm piston, verses the out dated 26mm # 3936316. You can feel the difference of the extra flow of the 30mm piston.
I wouldn’t waste my time and $ buying the cheap crap. The words, "you get what you pay for" is true 90% of the time.
