One of the guys in our club has a c6 vert with the z51 package ! The other day he was out riding and started smelling gas fumes very strong ! He had it towed to the dealer and they found that on the fuel lines where they run by the trans they have two clamps on them and one is slotted ! The clamp had slid and the fuel line rubbed a hole in the fuel line and it was dripping on the exhaust ! They checked another C6 and it was also doing the same thing ! Please beware ! His car only has 3k on it !
