I can't tell you it's because you're buying cheap pumps from Napa, but I wouldn't do that myself, even if it's worked out for other people. I believe mine is original, but I don't know for sure, and I sure haven't replaced it, so I don't have anything more interesting to tell you than that unless you want to know more about the vac troubleshooting procedure.
