no i cant and i cant see whats left because the o2 is like al the way on top of the pipe, i can only see whats in front of me. but now he wants to cut the pipe off and then put it back in with clamps.i was thinking of drilling a hole just below it and beside it so its easier to get to next time.and with the old one in there and disconnected will it still screw up everything with the new o2 in there.
