Gas tank was loaded with Rust, Internet told me to put viniger in it and let it sit for a few days worked great got all the rust out but then it came right back!! How do i stop it from coming back??

Vinegar again. Rinse,Baking soda to stop that process, Put oil in it and swish it all around to coat it if you're not using it . Or fill with gas to the top and ride.

What he said ^ I used vineager on my klt to clean up my tank, and baking soda and water swished that around to neutralize the vineager, just filled with gas and it's been fine

Instead of oil after acid/base flush I fill with diesel and drain then gas and ride. Just my preference...
