Mx495, Were you able to determine what was causing this? I recently replaced a jet pump on my spa and I'm having the same issue where the seal blows out the back of the wet end. Usually it survives the first start, but if I turn off the pump and turn it on a second time, there is a clicking sound followed by water gushing out of the back of the wet end. I've tried a few different things and I'm still having the same problem with brand new pump and seal.
