The tank is vented through the carbon canister via some rubber and metal lines that run from the tank to the carbon canister which is located in the passenger side front fender. This system allows air to be drawn INTO the tank but NOT be vented from it except when the PCM commands the CCPS (carbon canistor purge solenoid) to open and vent the tank into the canistor, and then into the combustion chambers via vacuum lines to burn up and vapor. You should NOT be able to draw any air out of the tank when the engine is NOT running, you SHOULD be able to draw air into the tank when the engine IS running. The tank vent and EEC (Evaporative Emmissions Control) system needs to be evaluated by someone who knows what they are doing, it's sounds to me like the tank is not being vented properly causing and intermittant vacuum lock in the fuel supply system. This could very likely be nothing more than a defective check valve at the carbon canistor.
