Previously in this forum I mentioned a fuel odor, had it checked out and was told there are no leaks. I was looking at my rear shocks and noticed a fuel line from the top of the gas tank that is all rusted and look like it corroded through in places. Is this line netrimental to the Jeep, how much would it cost to replace it, would it be easy to replace, etc...?

ALso, if anyone could tell me the best way to remove the upper bolts on the rear shocks I'd appreciate it....ty
