Yes the o-rings seem a little skimpy. After several failures it was determined that all blocks and fittings would be checked for tightness. We found many that were not tight and have not had a failure since. Also we have found some hoses that were not properly clocked and after a premature failure on right drive pump hose, where the hose was rubbing on the corner of the pump. Easy to loosen and reposition. I guess it depends if your cat was assembled on a Monday or a Friday.
