by John from Sidney, Ohio on September 15, 2013
Worked great - solved my problem of hard start for my I/O. It used to take 20-30 seconds of engine cranking before the engine started but now it starts in 1 second. Fuel restriction and leak back was the apparent problem with the old valve. The new valve has a larger flow passage for the same outside dimensions. Je42

Full StarFull StarFull StarFull StarEmpty StarIt's an anti-siphon valve...
by Jim from Tolono, Illinois on September 15, 2013
And it's the only one iboats has, so if you need one....buy it. It works. It's aluminum, I would have preferred brass, but I like iBoats, so I got it. Remember..this valve keeps you bilge from filling with fuel if a hose cracks or leaks.....so you need to have one.
