WHAT IS LEGAL?

Aluminum Tank & Tank Accessories, Inc.,  fuel tanks and fuel systems meet or exceed all DOT and EPA regulations. We Strive to provide you with the peace of mind in knowing anytime/anywhere your truck is inspected, you will have a legal fuel tank and fuel system. The following are the basic guidelines (not a complete listing) you need to know when deciding on an auxiliary tank for your truck.

There are many state and federal regulations on fuel tanks and fuel systems that you must comply, such regulations from the Enviromental Protection Agency, Federal Motor Vehicle Safety Standards, Vehicle Equipment Safety Commission, National Fire Prevention Association, and the Recreational Vehicle Industry Association. 

GRAVITY FEEDING IS ILLEGAL

Here are some laws (regulations) which pertain to gravity feed fuel tanks, and why they are illegal.

1. 49 CFR CH.III (393.65) 6d; Gravity or syphon feeding is prohibited.

2. 49 CFR CH.III (393.67) 7.4.5.; Fuel withdrawal fittings. The fittings through which fuel is withdrawn from a tank must be located above the noraml level of fuel in the tank when the tank is full.

In other words, the fuel must come from the top of the tank and not from a fitting on the bottom. For safety reasons, all aluminum tanks manufactured by ATTA will have no fittings on the bottom. When in doubt, look at your factory tank.

ATTA Fuel Tanks meet or exceed the following regulations

FMVSS 301

1. Safety Venting System. A liquid fuel tank with a capacity of more than 25 gallons of fuel must have a venting system which, in the event of fire, will prevent internal pressure from rupturing the tank's body, or seams.

2. Each fuel tank must be equipped with a non-spill air vent (such as a ball check valve). The air vent may be combined with the fill-pipe cap or safetry vent.

ATTA tanks have a minimum of two sources of vents. Atta sending units come with an anti-siphon ball check valve vent and we use an OEM style pressure relief cap.

3. Fuel tanks must be clearly and permanently marked with the manufacture's name, manufacture date, gallon size, and must state "Meets all FMCSA requirements for non-side mounted fuel tank", and "not to exceed 95% of capacity."

VESC-22

1. The fuel connections from the auxiliary fuel tank to the primary system, including a selection control valve, shall not render inoperative any of the functions of the primary system. The auxiliary fuel tank lines, fittings, valves, and connections shall, for purposes of fuel flow, be of a size at least equal to the primary system.

Basically, No connections or selector valve can prevent the factory fule system from working in normal functions from any part failure. if the selector valve fails, it cannot prevent the factory system from working. No portion of the selector valve or fittings shall be of smaller size than the factory fuel lines that might restrict fuel flow.

"When in doubt, do it right the first time. The enviromental wackos show no mercy"
