Good point on the "no room for expansion" however, I have looked over the fuel system on the rig and the vent tube only goes from the tank to the top of the gas fill area. It is completely closed loop. The only way I see the tank can vent is from the cap or maybe on top of the tank where the Generator picks up the fuel from. I can't see the top of the tank though.
You are not looking at the vent tube others are refering to. Yes, there is the tube that allows air to come up to the fuel inlet that prevents fuel from bubbling back on you while filling. The vent tube that others are refering to comes from the top of the tank and goes to a vapor recovery canister. By filling it up to the top of the fill tube neck, you are causing the problem as there is no room for expansion of the fuel as the temp rises during the day.
Instead, use a dipstick to check the level of fuel in the tank. As you check it over time it will initially drop until it reaches a stablization level. At that point is will be low enough that it no longer goes out the vapor recovery line. You "problem" will then be solved.
