I'm less worried about the rust than I am about the anti-drainback valve. It seals against the cardboard endcap, and they are notorious for leaking and causing poor startup lubrication. We had at least one guy on here who had a startup rattle caused by that, and if you search online you'll find many more.
Junk them and buy something better.
