Hi everyone. So I'm having an issue with my generator. I have two fuel tanks on board that's feeding the generator, each with its own open/close valve. The generator is getting fuel from the right tank, but not the left. I keep both valves open and the right tank depletes much quicker than the left. I closed the right valve to have the generator run off of the left tank, but the generator died from fuel starvation. I changed the water/fuel separator and inspected the fuel line from the tank to the separator and there were no issues. The fuel line had fuel in it between the tank and separator, for what it's worth. I then opened the valve for the right tank and it ran fine again. Any ideas what the problem could be?
