Ok. I still want to know why he switched.
I disliked the intake and output that came with the fx6 and had a leak problem similar to yours. The vinyl hose+pipe clamps are much more secure and reliable but I had this running through drilled bulkheads in my tanks.
Another idea, how about just trimming the broken end and reattach it to the fitting? You may have to elevate the fx6 a bit to compensate for the trim.
