Interestingly, as we're talking about aluminum oxide.....the thin layer of al oxide that forms naturally on bare aluminum is said to have the hardness equivalent of a sapphire, which is easy to understand since the most common naturally occurring aluminum oxide crystal is corundum, and sapphires and rubies are gem quality forms of corundum.

Thats because Saphires are aluminum oxide(Al2o3)

You need to realy check to see if those are not Stainless, they look stainless

That would be one doggone expensive tank if it's stainless!

If she were mine I would replace with a polly tank and be done with it. Make sure the fittings and sender are easily accesable.

Metallic tanks don't belong on most boat anymore. Polly is a much better product these days. I may be wrong....but I personally don't know of many boatbuilders using aluminum tanks anymore. (my opinion yours is alum.)

There are wat to many variables in installing and/or repairing an alum. tank that can come back to haunt you.

I'm just thinking of your safety and your wallet.

Good Luck!
