Hello, on my 1990 120hp Force I have been using a 6 gallon outboard metal fuel tank, I keep 2 of them in the boat if I need more gas. The boat does have a built in tank but I just don't want to load up the tank and then worry about the gas getting old if I don't use it up. The tanks have been no problem, the motor has run great for 3 years about a dozen time a season. Now here is my situation, I took the boat out today and it ran great. When I got back in to the dock and went to turn the key off the motor just stalled out, it was at an idle in neutral. I didn't think much of it, I thought the gas might have just ran out. When I got home after about an hour I noticed gas coming out of the lid (from the carbs, motor was at an angle) Pressure had built up so much in the 6 gallon gas tank because it was about 110 degrees so it was just pouring out from under the lid. These aren't vented tanks, I would call them one line pressure tanks, I'm sure you know the type. I opened the 6 gallon gas tank lid and whoooooshhhh! the pressure released big time. I cleaned the plugs. My problem now is that I'm trying to start the motor and gas is running out of the little tiny weep hole in the lower of the 2 carbs, starts up then stalls. Would that be a stuck open float? Should I alway have the tank vented even if it means loosening the cap? I know this is a long winded story but I tried to explain the best I could. Thanks in advance for any input.
