The length of the coupling part that fit over the lifter housing is only 1/4 long in some of the couplings should be longer than 0.4, The inner hose clamp barely rides on the lifter housing! Thanks. Haim

The bigger inner Id where the seal rides on the lifter housing should be around 0.45 long (deep), I revived 2 pc that have 0.375 deep and the rest around 0.25 deep, It is almost impossible to mount the hose clamp on the lifter housing without the seal slipping out.
