I did a preliminary disassemble and it comes off. 2 of the flaps fell out. I have 1 more complete tank and pump that is better than the one I was working on, When I get time I'll dig into it more.I never had to replace it, but took mine all apart and cleaned the crap from it. Not sure, but I don't think you can take it off.
