It's just strange that I can't recall any failures with these when I installed them...
That one E series I had it had a huge leak. It had just gotten stc update and both tubes 6 months prior... Left side was blown out big time. Put it back together, oh shit the pump leaking too wtf, they biffed the o ring on the 1 piece stc... Re psi tested after installing new, **** the right side tube is blown too... All 3 parts the prior shop installed all blown o rings... What the **** did they use on install??..?
That was tough to explain to customer that everything he just paid to have changed.... Was blown again...
