FuelCan Maintenance


Made In The USA


Universal Storage Systems Wall Cans are not portable fuel containers and must be structurally secured to floor or vertical wall assemblies. It is in direct violation to the intent of this product to be hard piped directly into any combustion engine or fuel system. The physical location, mounting, piping, assembly, maintenance, fluid content, filled volume, actions of filling, dispensing, use, and total compliance with all Federal, State, County, Local Regulations is the Sole Responsibility of the Owner and or the End User of this Product.

Prior to any Fuel Storage or Use

Fuel storage is becoming an important part of our everyday lives. Fuels are highly flammable liquids and should be stored only when you are aware of the safe and proper methods of storage. It is extremely important to realize the dangers of storing highly flammable liquids.

Wall Can Locations

  • Universal Storage Systems Fuel Cans must be located in environments with adequate ventilation, windows or vents. Do not mount your Wall Can in an area that is less than 50 feet away from open flame sources.
  • Located your Wall Can in an area where there is little or no direct sunlight or heat sources such as furnaces or space heater.
  • Read the label on any chemicals stored close by to know whether or not it's safe for you to mount your Wall Can nearby those chemicals because the vapors from the fuel will collect in the room or trailer.

Filling & Dispensing

Locate the "Max fill line" on the front side of your 30 Gallon Wall Can. You cannot fill past this molded level line. This allows for air space in the container, which allows the gasoline to expand and contract as the temperature changes. Our Wall Cans are designed to handle this potential increase and decrease in volume. Do not fill above the “Max Fill” molded line!

*   The volumetric coefficient of thermal expansion for gasoline is about 0.000528 per degree F. Gasoline expands about 1% with each 20-degree F increase in temperature.

Always take steps to discharge static electricity as this can build up on you or the storage container. Always turn off your cell phones and the engines on your equipment during any fueling operation.

Fuel spills can be picked up with paper, rags, cat litter or sawdust. Dispose of spill material at a hazardous waste facility, and never place them in garbage bags.

Aging Fuel

Long term storage of fuel requires treatment with additives such as Sta-bil, protection from moisture and proper rotation of your stored fuel to maintain quality.
Use a fuel stabilizer for long term storage. Add the stabilizer to the container before you fill it so that it is well mixed. The stabilizer may extend the life of gasoline and diesel up to 12 months.

It is important not to skimp―follow the manufacturer’s directions for the amount to add.

Don’t try to keep fuel too long. It is a good practice to rotate your fuel supply. When purchasing fuel, add stabilizer and keep it for six to eight months. Then pour it into your car’s gas tank or use it in the lawnmower or generator. Replace the fuel as you use it.

For Diesel, additives are recommended due to variations in diesel fuel quality around the world which can adversely affect today's precision fuel injection systems.

Diesel has a much longer shelf life than gasoline. Poor quality diesel fuel can cause performance issues, premature wear, gumming of components, and plugged filters.

To resolve these issues and to provide protection of the fuel injection systems, additives should be added after 3 to 4 months of storage.

Regularly check the fuel containers in storage for damage, leaks or signs of wear. Always make sure the area is ventilated.

Portable and Standby Generators

Never fill a generator when the engine is running or when it is hot. Always shut off the generator and allow it to cool before filling it. A spill on a hot engine can quickly turn into a fire or explosion when the spilled fuel ignites.

A 2000 watt generator will operate two or three small appliances and provide some lights, or perhaps one large appliance. At half load, this generator will use five gallons of gasoline in about one day. As generator size increases, so does fuel usage.

A 5500 watt portable generator will burn 7 gallons of fuel in just 10 hours at 50 percent load, and usage can easily double at full load to 14 gallons.

Just having enough gasoline on hand is only half the problem. The other half is finding and stocking up on fuel if an outage continues. Have your Wall Can reserve filled, that’s the priceless convenience in any emergency!
