Unfortunately, we do not recommend any sprayers be used for any types of fuel as they are combustible, and that would include the B&G 1 Gallon Sprayer Pistol Nozzle 4-Way Tip (N114-S). You can contact the manufacturer B&G at 800-544-8811 for a more accurate product recommendation if one is available for you.
As long as the product you're using can be used in a pump sprayer you can use the B&G 1 Gallon Sprayer Pistol Nozzle 4-Way Tip (N114-S). We do not recommend leaving anything in the tank overnight or pressurized. To maintain the sprayer in good condition, it is recommended to rinse the sprayer after being used and let it air dry.
