DONT FOLLOW PRINTED INSTRUCTIONS!

DON’T FOLLOW THE INSTRUCTIONS ON THE BOX!!! It says recommended torque is 42 lb/ft. You know what happened at 32lb/ft? One of bolts broke! And I was lucky there was long enough piece sticking out to remove it without drilling out! Check photos.

No leaks!!<br />Ordering was a breeze. Shipping was fast and I live way out in the middle of the Pacific Ocean, Hawaii. Price was much better than competition.
