Other Fuel System Hoses Lines/piping, And Fittings problems of the 2007 Honda Odyssey

Van has a constant tighten fuel cap warning on dash. Mpg has dropped off. Strong fuel odor in car when I fill tank. You can smell gas when you walk up to the car and it has been parked.

Takata recall, I took my go to walmart to change the engine oil and filter and the guy that changed, notice that the tank was leaking fuel from the top of the tank, I have let me know what was happening so, I decided to took the go with my mechanic. I used a camera to see on the very top of the tank and I saw the fuel leak coming from the top inside of the tank, he said it comes from the pump fuel system, so I see why my full tank doesn't get me the miles that it suppose to get by gallon. That's why we always notice the van that smells like gas and parking when we can see the gas on the floor. I was thinking it was water coming that from the air condition. . I'm worry about the combination of heat and gas that can cause fire. I live in texas and here the tempeture is really hot.
