my 01 ls has a bad leak somewhere in the top of the tank. I have searched with no luck all I found are the recalls for the 04-05 years.If anyone knows how to replace one I would be soooo grateful for any help on this you guys seem to know pretty much everything about the 01 ls and have been a huge help with my other ailments.Surely somebody has had to replace one before and I am hoping its not too difficult.thanks
