Having a fuel tank issue driver

that's exactly what's happening to me right now my love tank keeps draining faster than the right tank and I noticed as I go up a hill or when I stop I'll notice that the right ventilation too it's been leaking because there's a fuel underneath my fuel tank on the top the left side does not do that it's never done that that tells me that there's a problem with the right side that is why I am going to change the vent to on the right side and hopefully it will level off properly
