I have a 2001 1851 DC and need to locate my anti-syphon valve. Anyone know where this is? I heard it could be either in the fuel tank or near the stern (close to the bulb). I looked around and can't seem to find it. FYI I'm getting a loss of acceleration around 3,000 RPM's which does not seem to be related to water in the fuel. I heard the Anti syphon valve may need to be replaced. Thanks! Joe
