The o ring came out 100% undamaged, looks good as new. The top was leaking as well as all around the case. The bolts were tight enough too !

Reinstalled last night with regular thicker black o rings from hardware store, so far so good.. if this thing leaks again however Im going w a new or reconditioned pump for exchange.

*!*!* 1 week later not leaking anymore with a black buna-n style o ring, thicker and seems to have sealed great!
