I think mines a replacment tank, it's in great shape other than I don't know what's rolling around the bottom of it. Can you or how do you get them cleaned out, think some just almost automatically replace as a part of restoration of car?
There are a few threads on here. Consensus is that it's better to replace... Because of it is really rusted out you'll put a ton of work in and there aren't any guarantees it'll clean out all the crud
