1. RDS Manufacturing 30-Gallon Aluminum Transfer Tank: Best Overall
The RDS 30-gallon aluminum transfer tank is a top contender for its balance of capacity and weight. In our evaluation, the aluminum build offers excellent corrosion resistance, which is critical for longevity, especially in humid environments. The 12V pump delivers a solid 15 GPM, and the automatic shut-off nozzle adds convenience and safety. Owner feedback consistently praises the straightforward installation and reliable performance.
However, aluminum is softer than steel, so it can dent if heavy items shift in the bed. This tank is best for those who want a lightweight, rust-free solution and don’t need extreme impact resistance. Skip it if you frequently haul heavy, shifting cargo that could damage the tank.
- Lightweight aluminum construction resists corrosion and meets DOT standards
- Includes 12V pump with 15 GPM flow rate and automatic shut-off nozzle
- Mounting brackets and hardware included for easy installation in truck bed
Pros: Corrosion-resistant aluminum lasts longer than steel; Integrated pump and nozzle simplify fueling
Cons: Aluminum is more prone to dents than steel
2. Better Built 30-Gallon Steel Transfer Tank: Runner Up
The Better Built steel transfer tank is a rugged workhorse. In our research, the thick steel and powder coat finish make it highly resistant to dents and abrasions, ideal for job sites. The 12 GPM pump is adequate for most fueling tasks, and the lockable cap is a nice security feature. Owner feedback highlights its durability over years of heavy use.
On the downside, steel is significantly heavier than aluminum, which eats into your truck’s payload. This tank is best for those who prioritize toughness over weight savings. Skip it if you need maximum payload capacity or frequently move the tank in and out of the bed.
- Heavy-duty steel construction with powder coat finish for durability
- 12V pump with 12 GPM flow rate and manual shut-off nozzle
- Includes fill cap with lock and fuel gauge
Pros: Very durable steel resists dents and abuse; Lockable fill cap adds security
Cons: Heavier than aluminum, reducing payload capacity
3. Northern Tool 55-Gallon Diesel Transfer Tank: Large Capacity
The Northern Tool 55-gallon tank is designed for those who need to haul large volumes of diesel. In our evaluation, the manual pump is reliable and avoids electrical complications, but it’s slower than electric options. The tank meets DOT standards for safety, with a pressure relief valve and grounding provisions. Owner feedback notes that installation is straightforward and the tank fits most full-size trucks.
The main drawback is the manual pump: it requires physical effort and flows at only 8 GPM, making fueling a workout. This tank is best for off-grid users who don’t have power or prefer simplicity. Skip it if you need fast, effortless fueling or have a shorter truck bed (55 gallons takes up significant space).
- 55-gallon capacity for extended fueling range
- Manual rotary pump with 8 GPM flow, no electrical needed
- DOT approved with pressure relief valve and grounding lug
Pros: Large capacity reduces refill frequency; Simple manual pump works without power
Cons: Manual pumping is slower and requires effort
4. Westeel 45-Gallon Rectangular Transfer Tank: Space Efficient
The Westeel 45-gallon rectangular tank is engineered for bed space optimization. In our research, its shape allows it to fit snugly against the cab, leaving room for toolboxes or other equipment. The 12V pump operates at 10 GPM, which is adequate but not class-leading. Owner feedback appreciates the ability to close a tonneau cover over it, keeping it out of sight.
However, the flow rate is a bit lower than similar-sized tanks, and the steel construction adds weight. This tank is best for those who need to maximize usable bed space and want a low-profile solution. Skip it if you need higher flow rates or prefer aluminum for weight savings.
- Rectangular shape maximizes bed space and fits under tonneau covers
- 12V pump with 10 GPM flow and manual nozzle
- Low-profile design with anti-siphon fill neck
Pros: Space-efficient shape leaves room for other gear; Low profile allows tonneau cover use
Cons: Slightly lower flow rate than some competitors
5. FuelSafe 25-Gallon Polyethylene Transfer Tank: Lightweight Portable
The FuelSafe polyethylene tank is a lightweight option for those who need portability. In our evaluation, the plastic construction eliminates rust and is much lighter than steel or aluminum, making it easy to lift in and out of the bed. The 8 GPM pump is on the slower side, but the translucent body lets you see fuel levels at a glance. Owner feedback notes it’s great for occasional use and small trucks.
However, polyethylene is more susceptible to cracking under extreme impact or UV damage over time. This tank is best for light-duty users who prioritize weight savings and don’t abuse their gear. Skip it if you need maximum durability or plan to leave the tank in the sun constantly.
- Lightweight polyethylene won't rust or dent
- 12V pump with 8 GPM flow and manual nozzle
- Translucent body allows visual fuel level check
Pros: Very lightweight and easy to move; Translucent tank for quick fuel level checks
Cons: Polyethylene less impact resistant than metal
6. Transfer Flow 40-Gallon In-Bed Fuel Tank: Premium Build

In our research, the aircraft-grade aluminum and meticulous welding ensure longevity, backed by a 10-year warranty. The 15 GPM pump is fast and reliable, with thermal overload protection. Safety features include a rollover valve and UL listing. Owner feedback is overwhelmingly positive about build quality and performance.
The downside is the cost, which is significantly higher than comparable tanks. This tank is best for professionals who demand the best durability and safety, and are willing to pay for it. Skip it if you’re on a tight budget or only need occasional use.
- Aircraft-grade aluminum with 10-year warranty
- High-flow 15 GPM pump with thermal protection
- UL listed and DOT compliant with rollover valve
Pros: Excellent build quality and warranty; High flow rate and safety certifications
Cons: Premium price point
7. Dee Zee 30-Gallon Steel Transfer Tank: Budget Friendly
The Dee Zee 30-gallon steel tank is a no-frills option for budget-conscious buyers. In our evaluation, the manual pump is slow at 6 GPM, which can be tedious for larger fills. The steel construction is durable but the powder coat can chip over time, leading to rust. Owner feedback is mixed, with some praising the value and others noting pump issues after a few uses.
This tank is best for those who need an occasional backup tank and want to spend the least. Skip it if you fuel frequently, need fast pumping, or want long-term durability.
- Economical steel construction with black powder coat
- Manual rotary pump with 6 GPM flow
- Includes fuel gauge and locking cap
Pros: Lowest price point in the category; Simple manual operation
Cons: Very slow pump flow at 6 GPM; Steel prone to rust if coating chips
Frequently Asked Questions
How do I choose the right capacity for my transfer tank?
Consider your typical fueling needs and truck payload. A 30- to 40-gallon tank is common for most users, balancing capacity and weight. Larger tanks (55 gallons) are heavy when full and may exceed payload limits on smaller trucks. We recommend checking your truck’s payload rating and accounting for the weight of the tank plus fuel (diesel weighs about 7 lbs per gallon).
Are transfer tanks DOT approved?
Most reputable transfer tanks are DOT approved for on-road use, meaning they meet safety standards for pressure, leakage, and rollover protection. Look for tanks with DOT compliance labels. All tanks in our guide meet DOT standards except where noted. Always verify the tank is certified for the type of fuel you plan to carry.
Can I use a transfer tank for gasoline?
Transfer tanks are typically designed for diesel fuel, not gasoline. Gasoline has different volatility and safety requirements. Using a diesel tank for gasoline can be dangerous due to vapor pressure and material compatibility. If you need to transfer gasoline, look for tanks specifically rated for gasoline, often made of steel or specialized polyethylene.
Do I need a pump, or can I gravity feed?
Most transfer tanks come with either a manual or 12V electric pump. Gravity feeding is not recommended because it’s slow and unsafe due to lack of flow control. A pump ensures a controlled, safe transfer. Manual pumps are simpler and cheaper, while electric pumps offer faster fueling with less effort.
How do I install a transfer tank in my pickup?
Installation typically involves securing the tank in the truck bed using the provided mounting brackets or straps. Ensure the tank is firmly anchored to prevent movement during driving. For electric pumps, you’ll need to connect to the truck’s battery (usually with a fused harness). Always follow the manufacturer’s instructions and consider professional installation if you’re not comfortable with electrical work.
