Best way to find out where a fuel leak is located is by using a smoke machine. The fuel leaks on lgt's are usually in the engine bay, however, that doesn't mean there couldn't be a leak from a fuel line under the car or the tank. . If anything, it is quite annoying. I had to deal with a fuel leak on the same line twice in my lgt . I will be replacing that line and clamps for it in the spring/summer. If anything, have your local mechanic check it out. They have the equipment to locate it, because fuel leaks are one of the things that should be found and repaired quickly.
