Are both of the ends the same thread? Can you turn the hose over and attach it the other way? The reason I ask this is because you could get two male adapters, one for the pump and one for the filter, and then get two female PVC adapters and put a pvc union vertically in the middle of the connection.
I have never seen the connector hose like yours, but I agree with you, I don't like it either. Funny what engineers will come up with, you have tried and true methods that have worked for decades, and all of a sudden they have to try some new way of doing things, and of course everyone who saw the design and plans had to have loved it. I love plumbing, always trying to reinvent the wheel.
