The rectangle gasoline aluminum auxiliary tank is the most popular in the lineup. Our standard gas auxiliary fuel tanks range from 30 to 65 gallons. If you want to keep most of your bed space check out our more slender aluminium fuel tank designs. We also have a lay down style that fits under most crossover toolboxes.
