Just want to share my story and see if anyone out there happening the same. Recently I bought a brand new sealed box vortex MP40 from lfs that label manufactured on may 2022 which last month, and what happen is the adaptor is WRONG, it can’t fit in! I immediately went check my old MP40’s adaptor and it’s different from this new one, good that I called ecotech and they able to replace me a correct one, so I feel they might have a some troubles if a tons of their wavepump were made around the same time could be all wrong adaptors .
