    still stock
    place some cardboard under your gas tank forward, check for leaks while its off, then start and see if it leaks, lines wear out over time, could be hole in tank or the gasket for the sending unit could be no good, even the filler neck could leak if no good, if no leaks then have the guys at your job check it if they think or it might not be anything or its above my knowledge

    Also could be your charcoal canister, any of the emission items that can go wrong can cause a rich fuel mixture.......
