I have a 99' Mobius with a 325 Indmar engine. I had the fuel pump changed a couple of years ago. This summer I started having problems with the engine not getting gas. The engine would start fine as soon as we hit the water but after a couple an hour or so the engine would slowly die and then would not start again. If I let the boat sit over night it would be fine until we hit the water again. The fuel pumps run. I have take the lines off before and after the filters. When it works gas pumps as it should. When I have the problem no gas pumps out. I read on a Supra community about someone haveing a similar problem. They found it to be their anti-syphon valve. Anyone ever have this problem? How do I get to the anti-syphon valve to check it? Thanks.
