My Gas Tank is not venting, this is not a filling problem, it is not venting as it is taking gas from the tank. I run about 5 Gallons of gas from a full tank and end up with a vacuum in the tank when I remove the gas cap. On one occasion my engine quit running as the pump could not overcome the vacuum. I'm sure it has to do with the Enviro system. Does anyone have a plumbing diagram to show how this works and how the hoses are hooked up. This is on a Bennington Pontoon 2016 SLX with a 70 HP Yamaha 4 Stroke engine.
