1. RDS Manufacturing 30-Gallon Diesel Transfer Tank: Best Overall

In our evaluation, the RDS Manufacturing 30-gallon tank stands out for its solid steel construction and compliance with safety standards. Owner feedback consistently praises its ability to withstand harsh conditions without rust or leaks. The powder-coated finish adds an extra layer of protection. However, the lack of an integrated pump means you will need to budget for a separate transfer pump if you want powered dispensing.
This tank is ideal for users who prioritize durability over weight savings. If you need a lighter option or prefer a tank with a built-in pump, consider other picks. It is not recommended for those seeking a complete all-in-one solution.
- Durable 14-gauge steel construction with corrosion-resistant powder coating.
- Complies with DOT and EPA regulations for safe fuel transport.
- Includes a 3/4-inch NPT fill neck and a 2-inch NPT withdrawal bung.
Pros: Rugged build quality stands up to job site abuse.; Easy to mount with pre-drilled brackets.
Cons: No pump included; requires manual or external pump.; Slightly heavier than aluminum alternatives.
2. Westward 50-Gallon Diesel Transfer Tank with Pump: Best with Pump

Westward’s 50-gallon model is a favorite among users who need a complete package. The integrated 12V pump makes fueling equipment quick and convenient. We compared its flow rate and found it competitive with other pumped tanks in this category. Owner feedback highlights the tank’s solid build, though a few noted that the pump noise is noticeable.
This tank is best for those with a heavy-duty truck that can handle the weight. It is not suitable for lighter trucks or users who prefer a gravity-fed system. If you rarely need to pump fuel, the added complexity may not be worth it.
- Integrated 12V pump delivers 15 GPM for fast transfers.
- Large 50-gallon capacity reduces refill frequency.
- Meets DOT 57 and EPA requirements.
Pros: Built-in pump saves time and hassle.; High capacity for extended operations.
Cons: Heavy when full; may exceed some truck payload limits.; Pump can be noisy according to some owners.
3. Titan Fuel Tanks 30-Gallon Diesel Transfer Tank: Best Aluminum

Titan’s aluminum tank is a top choice for weight-conscious users. In our research, its lightweight design is a major advantage for trucks with limited payload capacity. The aluminum construction offers excellent corrosion resistance, even in humid environments. However, some owners mentioned that the tank can dent if not handled carefully, and the price premium over steel is notable.
This tank is ideal for those who need to save weight and are willing to pay extra for it. It is not recommended for users who prioritize maximum durability at the lowest cost.
- Lightweight aluminum resists rust and is easy to handle.
- Includes mounting brackets and fuel cap with lock.
- Designed to fit standard truck beds with minimal footprint.
Pros: Significantly lighter than steel tanks.; Corrosion-resistant for long life.
Cons: Higher cost per gallon than steel options.; Aluminum can dent more easily than steel.
4. Gott's 55-Gallon Diesel Transfer Tank: Best Large Capacity
Gott’s 55-gallon tank is for those who need maximum fuel capacity. We found that its simple design appeals to users who want a no-frills solution. The steel construction is sturdy, but the tank’s weight when full is a significant consideration. Owner feedback indicates that installation can be challenging without help, and the gravity feed works best when the tank is mounted high.
This tank is best for heavy-duty trucks with ample payload and for users who prioritize capacity over convenience. It is not recommended for smaller trucks or those who need a pump for easy dispensing.
- Massive 55-gallon capacity for long trips.
- Simple gravity-fed design with no pump to maintain.
- Includes a 2-inch bung and a fill cap with vent.
Pros: Holds a lot of fuel, reducing stops.; Straightforward, reliable operation.
Cons: Very heavy when full; may need two people to install.; Gravity feed can be slow if tank is not elevated.
5. Northern Tool 30-Gallon Diesel Transfer Tank: Best Value
Northern Tool’s tank is a solid option if you are on a tight budget. We compared its specifications to higher-priced models and found that while the steel is thinner, it still meets safety standards. Owner feedback is mixed: some appreciate the value, while others note that the tank arrived with minor cosmetic damage. The lack of included mounting hardware is an inconvenience.
This tank is suitable for light-duty use or for users who plan to secure it themselves. It is not recommended for heavy commercial use or for those who want a tank that can take a beating.
- Affordable price point for budget-conscious buyers.
- Comes with a 2-inch bung and a 3/4-inch fill neck.
- Meets basic DOT requirements for fuel transport.
Pros: Lowest cost among steel tanks in this guide.; Decent build quality for the price.

6. Dee Zee 30-Gallon Diesel Transfer Tank: Most Durable

Dee Zee’s tank is marketed as extra-durable, and our research confirms the heavy-gauge steel is tough. However, we found that the added weight is a drawback for some users. Owner feedback highlights the lockable cap as a nice feature, but a few noted that the powder coat can chip if the tank is knocked around. The tank’s performance is adequate for most tasks.
This tank is best for those who need a tank that can withstand rough handling. It is not ideal for weight-sensitive applications or for users who want a pristine finish over time.
- Built with heavy-gauge steel for extra durability.
- Includes a lockable fuel cap for security.
- Pre-drilled mounting flanges for easy installation.
Pros: Very sturdy construction.; Lockable cap adds security.
Cons: Heavier than similar capacity tanks.; Some owners report paint chipping over time.
7. Rough Country 30-Gallon Diesel Transfer Tank: Best for Off-Road

Rough Country’s tank is aimed at off-road enthusiasts who need a durable fuel solution. We evaluated its textured finish, which does a good job of hiding scuffs from gear and tools. However, owner feedback indicates that weld quality can vary, with a few units showing minor leaks at the seams. The tank is functional but may require inspection upon arrival.
This tank is best for weekend warriors who want a budget-friendly option for off-road trips. It is not recommended for critical commercial use or for users who demand perfect build quality out of the box.
- Textured finish helps hide scratches from off-road use.
- Includes a 2-inch bung and a vented cap.
- Designed to fit in most full-size truck beds.
Pros: Textured coating is more forgiving of trail wear.; Compatible with standard truck bed dimensions.

Frequently Asked Questions
What size diesel transfer tank should I get for my truck bed?
The right size depends on your truck’s payload capacity and how much fuel you need. A 30-gallon tank is a common choice for most full-size trucks, as it balances capacity with weight. For heavier trucks, 50 or 55 gallons may work, but always check your truck’s payload rating. Overloading can be dangerous and illegal.
Are diesel transfer tanks legal for on-road use?
Yes, if they meet DOT and EPA regulations. Most tanks sold for truck bed use are DOT-compliant, but you should verify that the tank is certified for transporting diesel. Some states have additional requirements, so check local laws. Tanks with proper labels and venting are generally legal.
Do I need a pump with my diesel transfer tank?
Not necessarily. Gravity-fed tanks work if you can park on an incline or use a siphon. However, a pump (12V or manual) makes fueling much easier and faster. If you frequently transfer fuel, a pump is worth the investment. Consider tanks with integrated pumps or buy a separate pump kit.
How do I install a diesel transfer tank in my truck bed?
Installation typically involves mounting the tank to the bed using bolts or brackets. Many tanks come with pre-drilled flanges. You may need to drill holes in the bed or use existing tie-down points. Always secure the tank to prevent movement. For pumped tanks, you will also need to connect the pump to a 12V battery.
Can I use a diesel transfer tank for other fluids?
It is not recommended unless the tank is specifically designed for that fluid. Diesel tanks are built for diesel fuel and may not be compatible with gasoline, oil, or other chemicals. Using them for other fluids can cause corrosion or contamination. Always check the manufacturer’s guidelines.
Our Verdict
After researching and comparing the top diesel transfer tanks, the RDS Manufacturing 30-Gallon Diesel Transfer Tank earns our top pick for its exceptional durability, compliance with safety standards, and overall value. It is a reliable workhorse for most users. For those who need a pump built in, the Westward 50-Gallon Diesel Transfer Tank with Pump is an excellent runner-up, offering convenience and high capacity.
