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.
If this is a F53, then yes, there is a vent on top of the tank just right of where the fuel pump is located. It immediately tees off; one hose goes back a short distance and ends with a check valve that only allows air to vent into the tank. The hose on the other end of the tee heads forward to a charcoal canister near the engine. This is an emission control/EPA device that the engine sucks on to burn the vapors that escape from the tank.
