Re: About to make my first fuel tank
If you don't line your tank, it will rust. I am thinking of one thing that might work, but not sure. Engine paint is fuel resistant. I don't know if it is strong enough to prevent rust, but it might be. I have thought recently that when making your own tank, painting the insides of the metal before welding might be a cheaper alternative to buying tank liner. But I could be wrong. Perhaps someone more experienced would be able to shed some light on that.
