Vented loops are commonly used in the marine toilet system and engine cooling system. The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through.

Did its job
Got me back onto the water. The mounting holes distances from center to center are less than original equipment. But in a pinch they will do the job.
