My '92 Subaru Legacy recently developed a slow gas leak. It only leaks when it runs which leads me to believe that something is wrong with the fuel line. Around the same time that this happened, my car started dying out when slowing down. This leads me to believe that this is all because of a faulty fuel line. What gets me though is that the battery is completely dead once it dies and must be rejumped. The battery is fairly new so that is not likely the problem and the connections are good. Looking for some advice.
