What a pain!!
I ordered and received and set up today an Eheim spray bar attachment. It was wonderfully designed and fit great. Best of all, it had a cap you could unscrew and insert a funnel and prime just like the Filstar canisters. I guess Eheim figured out that at least some of their "easy" priming designs didn't work so well after all. They sure charge a lot for their accessories though.
The seals need lubed when it gets that hard. Mine came with a tube to lube up the seals.
I have always just pushed down on the primer to get it filled. Your water level will need to be pretty high for it to start.
The caps on the attachments are for cleaning the tubes out. The caps come on both the intake and output sides. I really like them. Every 6 months or so, I just run a brush down the tubes to clean out all the gunk that gets built up over time.
