Default Re: Rust in gas tank

Evaporust can be purchased at Home Depot or Harbor freight. Buy 10 gallons. Fill the tank with it. It turns the rust into liquid and you drain it out. Works well. It is a product made to do exactly what you need. I have used it on many tanks with 100% success. Regarding off season storage, you are always better leaving the tank full of fuel. Rust occurs when the tank has no fuel in it, due to condensation and humidity. If the tank is full of fuel, it cannot rust.
