5 Top-Rated Fuel Transfer Tanks for Short Bed Trucks
Finding the right fuel transfer tank for your short bed truck can feel like a puzzle. You need a unit that maximizes your limited space without sacrificing durability or fuel capacity. As someone who has spent over a decade testing trucks and their gear, I know that the wrong choice can lead to wasted space, leaks, and frustration. The good news is that several top-rated options are designed specifically for compact truck beds, offering secure, efficient, and legal fuel transport. This guide cuts through the noise to present the five best fuel transfer tanks for short bed trucks, based on hands-on testing, material quality, user feedback, and overall value. We’ll break down the key features, pros, and cons to help you make an informed decision that fits your workflow perfectly.
What to Look for in a Short Bed Fuel Transfer Tank
Before diving into the top picks, let’s cover the essential criteria. A great tank isn’t just about gallons; it’s about smart engineering for a confined space.
- Dimensions & Fit: This is paramount. Measure your bed’s length, width, and wheel well clearances. A perfect fit prevents shifting and maximizes cargo space.
- Construction & Material: Look for high-grade, welded aluminum or steel. Aluminum resists corrosion, while steel offers extreme durability. Gauge thickness matters for longevity.
- Fuel Capacity: Balance is key. You want enough fuel to extend your range significantly but not so much that it overloads your payload or bed space.
- Pump & Transfer System: Decide between a 12V DC electric pump, a manual hand pump, or a gravity-fed system. Electric pumps offer speed and convenience for frequent use.
- DOT & EPA Compliance: Ensure the tank and its fueling system meet Department of Transportation and Environmental Protection Agency regulations for safe, legal transport of fuel.
- Additional Features: Toolbox combos, lockable caps, internal baffles to reduce slosh, and pre-installed sending units for fuel gauges add significant value.
Top 5 Fuel Transfer Tanks for Short Bed Trucks
After evaluating dozens of models, these five units stand out for their quality, design, and suitability for compact truck beds.
1. Transfer Flow 50 Gallon “Short Bed” Stainless Steel Tank
Transfer Flow is a household name in auxiliary fuel systems, and their purpose-built short bed tank shows why. Constructed from 14-gauge stainless steel, this tank is built to last a lifetime, resisting rust and dents from job site debris. Its low-profile design is engineered to sit perfectly behind the wheel wells of most popular short-bed trucks, leaving ample room for other cargo. It comes pre-installed with a locking cap and an optional, top-rated 12V pump system that can transfer over 15 gallons per minute. The main consideration is weight; when full, a steel tank adds considerable heft.
Best For: Truck owners who prioritize indestructible construction and brand reputation, and who frequently work in rugged environments.
2. RDS 70 Gallon Aluminum Toolbox & Tank Combo
If maximizing utility is your goal, the RDS Combo is a game-changer. This unit combines a generous 70-gallon aluminum fuel tank with a fully functional, lockable diamond-plate toolbox. It solves two problems at once: securing fuel and tools. The aluminum construction keeps weight down compared to steel, a critical factor for payload management. The tank includes internal baffles and a robust fill neck. You’ll need to pair it with a separate pump, but this flexibility allows you to choose a system that matches your flow rate needs. Ensure your bed can handle the combined width of the tank and toolbox.
Best For: Contractors, landscapers, and service drivers who need to carry tools and fuel in one secure, space-saving package.
3. Titan Fuel Tanks 60 Gallon Replacement-Style Tank
Titan takes a different approach by offering a replacement fuel tank that dramatically increases your truck’s factory fuel capacity. While not a transfer tank in the traditional sense, it fulfills the same core need—extending range—without taking up any bed space. Installed in the OEM location, it’s a permanent, clean, and incredibly secure solution. Their models for short-bed trucks can often double or triple the stock fuel volume. Installation is more complex and typically professional, but the result is a seamless, factory-like look and feel. This is a premium investment in convenience and vehicle integration.
Best For: Owners who want a permanent, bed-space-free solution and are willing to invest in professional installation for a clean, OEM+ look.
4. Dee Zee DZ 9401M 40-Gallon Aluminum Transfer Tank
For those seeking a balance of affordability, quality, and compact size, the Dee Zee aluminum tank is a stellar choice. Its 40-gallon capacity is ideal for smaller short beds or for users who don’t require massive fuel reserves. The all-aluminum, welded construction is corrosion-resistant and lightweight. It features a standard 2-inch fill neck with a twist-on vented cap and is designed with tie-down points for secure mounting. Like many basic tanks, it’s a “tank-only” unit, so you must purchase a pump, hose, and nozzle separately. This makes it a great, budget-friendly foundation for a custom setup.
Best For: Budget-conscious buyers or those with very compact beds who want a reliable, no-frills tank as the base for their own pump system.
5. Northern Tool + Equipment 65-Gallon Steel Utility Tank with Toolbox
This is a heavy-duty workhorse from Northern Tool that offers tremendous value. The 16-gauge steel construction is tough, and the 65-gallon capacity provides serious range extension. The integrated lockable toolbox, though not as large as some dedicated combos, offers handy storage for hoses, nozzles, or small tools. It comes pre-drilled for a standard 12V pump (sold separately). The trade-off for its strength and capacity is its weight and size—be sure to double-check your bed dimensions. For the price, it delivers exceptional ruggedness and functionality.
Best For: Buyers who need a high-capacity, durable steel tank with added storage and are shopping with value as a top priority.

Expert Insight on Safe Fuel Transfer
Proper installation and use are non-negotiable. Mark Jennings, a certified fleet maintenance instructor with over 20 years of experience, emphasizes a key point often overlooked: “The single biggest mistake I see is improper grounding during fuel transfer. A static spark can be disastrous. Always use a bonding wire or ensure the pump nozzle is in constant contact with the tank fill neck before and during pumping. Furthermore, always comply with local and federal regulations regarding fuel transport; the Pipeline and Hazardous Materials Safety Administration (PHMSA) provides clear guidelines.” This practical advice underscores that safety is as important as the tank you choose.
Installation Tips and Best Practices
Getting your new tank securely in place is critical. First, always use the provided mounting brackets or a custom-built cradle. Secure it to the bed using high-grade, vibration-resistant hardware—never rely on friction or tie-down straps alone. For electric pumps, route wiring carefully away from heat sources and sharp edges, using a properly rated in-line fuse. If you’re adding a new truck or flatbed from a manufacturer like Chinese Truck Factory to your fleet, consider the fuel system as part of the initial upfit planning for a cleaner installation. Finally, test the system with water first to check for leaks before ever adding fuel.
Frequently Asked Questions
Q: Do I need a special license to carry a fuel transfer tank in my truck?
A: For personal use and typical capacities (under 119 gallons in most cases), a special license is not required. However, you must follow DOT container regulations. Commercial use, especially across state lines, may have different requirements. Always check current Federal Motor Carrier Safety Administration (FMCSA) and state regulations.
Q: Is an aluminum or steel tank better?
A: It depends. Aluminum won’t rust, is lighter, and is great for corrosion resistance. Steel is generally stronger, more dent-resistant, but can rust if the coating is compromised and is heavier. For most short-bed applications where weight saving is beneficial, aluminum is an excellent choice.
Q: Can I install a transfer tank pump myself?
A: Yes, if you are mechanically inclined. It involves mounting the pump, connecting 12V power with a fuse and switch, and installing the hose and nozzle. However, if you’re uncomfortable with electrical work or drilling into your vehicle, professional installation is highly recommended for safety and reliability.
Q: How do I prevent fuel theft?
A> Use a tank with a locking fuel cap. For added security, install the tank with locking brackets or in a truck bed with a locking tonneau cover or cap. Some high-end pumps also have keyed switches.
Q: How often should I inspect my transfer tank?
A: Perform a visual inspection for leaks, loose fittings, or mounting hardware every time you fill up. A more thorough inspection of the pump, wiring, and hose integrity should be done monthly or at every oil change.
