I would give them a call to be sure which they have, or you can even ask Roger (rvitko)by PM how recent they are. Any of the pumps I have received from AquaCave have been the most recent stock, they have a very high turnover of Tunze. Usually every few weeks from what I gather.
For the rubber bump ons for the magent, PM Roger, he will get some out to you in no time.
