Spec'd Correctly Before It Ships

Spec'd Correctly Before It Ships

Wrong fuel system selection on an auxiliary tank means downtime, return freight, and a crew waiting on fuel. We eliminate that risk. Before your AT40TT-ED ships, Tank Vault confirms your Dodge 1500 ECO Diesel compatibility and verifies you've selected the correct fuel system — Freedom Fill or Push N. If you choose Freedom Fill, we confirm your vehicle year so the system arrives programmed for your truck. No guessing, no return shipments, no wasted days. This is the same pre-offer spec review process we apply to every industrial tank we sell — now applied to your auxiliary fuel setup.

Heavy-Gauge Aluminum Built for Field Use

Heavy-Gauge Aluminum Built for Field Use

The 40-gallon tank is constructed from .125 gauge aluminum — heavy-gauge material that handles rough job sites, gravel roads, and daily fleet use without cracking or corroding. Full internal baffling controls fuel movement, so you don't get the violent slosh that destabilizes payload on uneven terrain. Driver's side fill neck keeps refueling accessible without climbing into the bed. This is diesel-only construction — no compromises on material compatibility. The tank sits at 19 inches tall by 20 inches wide by 60 inches long, engineered specifically for the Dodge 1500 ECO Diesel short bed footprint.

Full-Length Toolbox Without Sacrificing Fuel Capacity

Full-Length Toolbox Without Sacrificing Fuel Capacity

The bolted-on aluminum toolbox measures 9 inches tall by 20 inches wide by 60 inches long — a full-length single-lid compartment with dual paddle latches that secures your gear, tie-downs, and site supplies. It turns dead bed space into organized storage without sacrificing fuel capacity. The toolbox is not an aftermarket add-on — it's integrated into the tank design and bolted directly to the top. For fleet operations where bed space is at a premium, this combo eliminates the tradeoff between carrying extra fuel and keeping tools accessible and protected from the elements.

“Ordered the 40-gallon combo for my '22 ECO Diesel short bed. Tank Vault confirmed my Freedom Fill selection and model year before processing — no surprises on delivery. Toolbox holds what I need, baffled tank doesn't slosh on the lease roads. Installed in an afternoon with no issues.”

    Fuel System Options (Required to Select 1 Option) 

    • Choose either the Freedom Fuel System or the Push N’ Fuel System.

    Freedom Fill Auxiliary System

    The Freedom Fill Auxiliary System is the most popular fuel system option. It is a complete installation kit and comes with everything you need to install an auxiliary fuel tank to your truck.

    The Freedom Fill Auxiliary System is specifically designed to be used in conjunction with an auxiliary tank manufactured by Aluminum Tank & Tank Accessories, Inc. for current year model Dodge, Ford, and GM / Chevrolet diesel trucks.

    The Freedom Fill Auxiliary System is a computerized fuel system. When the factory tank reaches approximately 1/2 a tank, an auxiliary computer module will activate the fuel pump and begin transferring fuel from the auxiliary tank and will refill the factory tank to approximately 3/4 of a tank.

    The system is all automatic for peace of mind and ease of use. The pump will not turn on when the auxiliary tank is empty.

    Push N Fuel Auxiliary System

    The Push N Fuel Auxiliary System is an economic fuel system. Designed specifically for use in an auxiliary tank manufactured by Aluminum Tank & Tank Accessories, Inc. for use in only in Dodge, Ford, and GM / Chevrolet diesel trucks.

    The Push N Fuel System uses a momentary rocker switch mounted to the dash. The operator must push and hold the switch to activate the heavy duty rotary vain pump and hold the switch to activate the heavy duty rotary vain pump to begin the transfer of fuel from the auxiliary tank to the factory tank. When the switch is released, the pump will shut off.

    Frequently Asked Questions

    The AT40TT-ED is engineered specifically for the Dodge 1500 ECO Diesel short bed. Tank dimensions are 19 inches tall by 20 inches wide by 60 inches long. If you have a long bed or a different engine configuration, this unit will not fit correctly. Contact Tank Vault before ordering if you're unsure about your bed length — we'll confirm fitment based on your VIN or bed measurements.
    Freedom Fill automatically transfers fuel from the auxiliary tank to your OEM tank based on your vehicle's fuel level — it's programmed to your specific make and model year. Push N Fuel requires manual activation to transfer fuel. Freedom Fill is the hands-off option for drivers who want set-and-forget operation. Push N Fuel gives you direct control over when fuel transfers. Both systems are compatible with the AT40TT-ED. If you're unsure which fits your operation, contact us and we'll walk through the right choice for your use case.
    The AT40TT-ED ships via LTL freight to your location at no additional charge. Aluminum auxiliary tanks of this size require freight shipping — they cannot go parcel. Lead times vary based on fuel system selection and current inventory. Contact Tank Vault with your delivery zip code and needed delivery date, and we'll confirm availability before you order. If you need job-site delivery, liftgate service, or specific scheduling, let us know — we coordinate freight to match your timeline.
    Auxiliary fuel tank regulations vary by state. The AT40TT-ED is designed as a below-bed-rail diesel auxiliary tank for a specific vehicle application. ATTA manufactures these systems for on-road use, but your local jurisdiction may have specific requirements regarding auxiliary tank capacity, labeling, or venting. Tank Vault provides all available manufacturer documentation with your order. For state-specific compliance questions, we recommend verifying with your local DOT or fire marshal before installation. Contact us and we'll share what documentation ATTA provides.
    If the AT40TT-ED arrives damaged, doesn't match your selected configuration, or has a manufacturing defect, contact Tank Vault immediately. We resolve issues directly — no runaround. Our 30-day return policy covers uninstalled units in original packaging. Because we verify your fuel system selection and vehicle compatibility before the order ships, configuration errors are rare. But if one occurs, we coordinate the resolution including return freight if necessary. That's the same standard we apply to every product we sell.
    Yes, within our 30-day return window — provided the tank is uninstalled and in original packaging. Auxiliary tanks are vehicle-specific, which is why we confirm your bed length and engine configuration before the order processes. If you discover a fitment issue after delivery, contact us immediately and we'll coordinate the return. We'd rather catch the problem before it ships, but if it gets through, we handle it. Return freight for large items is coordinated through our LTL network.
