Good morning all, I am not really sure of my fuel problem. I think there were multiple issues. The boat runs great at idle speed, every time I hit the throttle, both engines would die. It happened 3 times. I found that the vent hose went from the gas think top, straight to the bottom of the boat. I have rerouted that. I also found that the fuel filter on the port side was full of water, varnish, everything but good gas. I have refueled just before that with 97 gallons, I also pulled 2 gallons of water out of the old gas when I put the boat in the water. I just changed the fuel filter on the port side so hopefully that will be good. The starboard side, every time I let the boat sit too long, it is hard starting, to the point I have to dump gas down the carb to get it going. I pulled the fuel filter and there was nothing in it but some rust....I mean not a drop of gas. Do you think that before I if Ed the vent problem that a vacuum was created in the tank and it pulled all of the gas back in? Would a new anti siphon valve keep the gas from going from the lines back into the tank? Nt sure what the issue is here or how to fix it. My guess would be to get a new anti siphon valve and maybe a fuel bulb inline just in case. Thoughts?
