880 will not store multiple pumps

You will need to replace that rubber cup shaped thing that acts as the check valve. In the pre 2000 880’s, it looks like a cup in the post 2000 880’s it looks like a cup with a hole in the middle. They are both sold on ebay. Older ones cost upwards of $20 because they are custom made.
Good luck.

Thanks for the reply. Rather than pay an outrageous price for the seal, I inserted two o-rings (20 cents) into the recess of the seal, on top of each other, to expand it, and it corrected the problem.
