Ya. This tank is not leaking and seems solid even around where the sending unit mounts. I'll let the professionals tell me if I should repair or replaced. We don't have Rockauto up here in Canada although we can get their stuff shipped to the border and pick it up. (I can't cross the border, but there are locals offering this service now.) I think a replacement tank is around $300. Typically repair should be cheaper and I prefer the metal tank over a replacement plastic one. Will be pricing stuff out today.
@TexasThat looks like a nice build you did! I don't intend this truck to be anything other than a hunting/fishing/zombie killer. I just want to be able to rely on it. The 460 with a 5 speed was not a common option, so it's worth putting in the time and effort to get it running.
