Where is it? What is it? What does it look like? How do you test to know if you have a bad one? Where can you get one?

Re: Anti - Siphon Valve

Mine is on the fuel tank between pickup hose and tank. Under the floor??? Are you sure it is bad??<br />I had a week fuel pump that would only empty the tank to 1/2 mark. I was thinking anti siphon or pick tube with a pin hole in the side. Changed both of them then found out it was the pump. How foolish i felt after all that work. Also make sure a mud dobber hasn't clogged up your vent this will also keep the pump from picking up fuel after running for a short spell. Maybe with more information someone can give you your pump specfication so you can check suction side. hope this helps

Re: Anti - Siphon Valve

I've read several references about anti-siphon valves in threads regarding intermittent fuel problems throughout this forum, but a search does not turn up anything under the term "anti-siphon valve". <br /> <br />So I figured it would improve the board to have information about this little gremlin for folks who wanted to search/know more about it (like me). I think this is exactly the type of unusual problem that could really frustrate the heck out of someone. It would be nice to have a succinct answer for guys to search on forever more. Perhaps someone could post a way to check / eliminate it from a diagnostic point of view too, or add a picture of one, or perhaps post a link on where to get one.<br /><br />BP212

anti siphon device aka fuel restriction device<br /><br />the valve the kind i've seen most is located on the gas tank disguised as an normal 3/8inch hose barb fitting.<br />these little guys have a spring and ball assembly<br />that can trap trash and block fuel flow.<br /><br />For a TEMPORARY test you can use an outboard fuel tank to bypass your boats tank <br />if problems go away the problem is valve, tank,lines or related to the fuel in boats :) tank. :)
