Fuel cans, tanks, and caddies are dedicated storage containers for the temporary transfer, transportation, and dispensing of fuels and other flammable liquids. Fuel and gas cans provide temporary storage for fuels in a portable, handheld container. Fuel caddies are larger than fuel cans, feature wheels or handles for mobility, and refill large containers or fuel tanks. Marine fuel tanks store fuels on boats and other watercraft while resisting the effects of consistent exposure to moisture. Portable fuel tanks hold high capacities of fuel to keep vehicles and equipment running in remote areas or on worksites. Diesel fuel filter carts provide a portable means to cleanse diesel fuel of contaminants and water prior to use.
