The only proviso about stainless tanks is surrounding corrosion. If you install a stainless tank (or any other stainless part for that matter) in a car you can create corrosion cells with any regular steel that comes into contact with it.

Of course the way a typical collector car is used (indoor dry storage, no winter use etc) there won't be an issue anyway. (which is why you don't really need a stainless tank ;-). But if you were to use it in a corrosive environment like driving year round or wet storage any regular steel that contacts the stainless will corrode many many times faster than it would otherwise.

This is because when stainless steel is paired with regular (carbon steel) the regular steel becomes the noble metal and it "sacrifices" itself to protect the stainless.

Anyone with a boat who ever put a stainless anchor and a regular steel chain knows this all too well when the last link of the chain that connects to the stainless anchor dissolves away!
