I also have pin holes in my existing tank. I bought a replacement from club spares at a very reasonable price and I’m in the process of cleaning it up ready for painting (photo below).

I just want to buy a new tank for my pickup like the original one, but they do not exist.
Might try some of the suggestions, such as citric acid to clean; but my tank has pin holes which I have covered with plastic metal on the outside. If I can move the internal filter out of the way, I might try sealant.
