  • Perfect fit - Easy replacement
Perfect fit. Easy replacement. I was horrified when I cracked the snorkel off the original. Thrilled that I found this replacement. The original screw head requires a socket wrench. The new one requires an allen wrench. The screw can easily be swapped out so you can choose what you prefer.
