All -- I could use some guidance. I'm tracking down a fuel leak and suspect the tank (removal will confirm). I know there are reasonable sealant options (POR 15 etc) but I have also considered a fresh start. 1) has anyone found a brand that fits properly, looks OEM and is not paper thin? 2) I assume a pro refresh is $300 plus? 3) is this the same tank as a 68 LeSabre? Thanks!!
