1. RDS Manufacturing 30 Gallon Aluminum Fuel Tank: Best Overall
The RDS Manufacturing 30 gallon aluminum fuel tank is a top contender for truck bed fuel storage. Its welded aluminum construction provides excellent corrosion resistance and durability. The tank includes internal baffles to minimize fuel slosh during driving, which enhances stability. Based on owner feedback, the included sending unit works well with most aftermarket gauges, though a few users noted compatibility issues with specific OEM setups.
However, this tank is not ideal for those requiring a simple gravity-feed system, as it is designed primarily for use with a 12V pump. Additionally, the aluminum finish can be prone to scratches if not handled carefully. If you need a robust, lightweight tank for a long-haul setup, this is a strong choice.
- Aluminum construction resists rust and corrosion
- Internal baffles reduce fuel slosh
- Comes with a fuel sending unit for gauge connectivity
Pros: Lightweight yet durable aluminum build; Easy to install with included mounting brackets
Cons: Some owners report sending unit compatibility issues with certain truck models
2. Transfer Flow 30 Gallon In-Bed Fuel Tank: Premium Pick
The Transfer Flow 30 gallon in-bed fuel tank is a premium option with a focus on safety and durability. It is UL listed, meaning it meets rigorous safety standards for fuel storage. The steel construction is powder coated to resist rust, and the lockable cap prevents theft. In our research, owner feedback highlights its solid build and reliable performance over years of use.
However, this tank is significantly heavier than aluminum models, which can affect payload capacity and fuel economy. It also requires a dedicated pump for fuel transfer, adding to the overall setup cost. If you prioritize safety and longevity over weight savings, this tank is a top contender.
- UL listed for safety compliance
- Heavy-duty steel with powder coat finish
- Includes a lockable fuel cap
Pros: Built to last with thick steel walls; Safety certifications add peace of mind
Cons: Heavier than aluminum alternatives
3. Northern Tool 30 Gallon Diesel Fuel Tank: Best Value
The Northern Tool 30 gallon diesel fuel tank offers excellent value for budget-conscious buyers. Made from rotomolded polyethylene, it is lightweight and immune to rust. The package includes a 12V pump and hose, making it a complete solution for transferring fuel. Based on owner feedback, it is easy to install and works well for occasional use.
However, the plastic construction is less durable than metal tanks and may become brittle over time if exposed to direct sunlight. It is also not recommended for gasoline storage due to permeation concerns. If you need a temporary or occasional fuel solution, this tank is a good choice, but for long-term heavy use, a metal tank may be better.
- Rotomolded polyethylene is lightweight and impact resistant
- Includes a 12V pump with hose
- No rust concerns
Pros: Affordable and corrosion proof; Ready to use out of the box with included pump
Cons: Plastic may degrade under prolonged UV exposure
4. Titan Fuel Tanks 30 Gallon In-Bed Fuel Tank: Heavy Duty
The Titan Fuel Tanks 30 gallon in-bed fuel tank is built for heavy-duty use. Its twin-wall steel design provides exceptional strength and puncture resistance. It is compatible with both diesel and gasoline, making it versatile for different truck setups. Owner feedback often praises its durability even in off-road conditions.
However, the tank is quite heavy, which can be a drawback for those concerned about payload. It also lacks a lockable cap, which some users see as a security issue. If you need a tank that can withstand harsh environments and don’t mind the extra weight, this is a solid option.
- Twin-wall steel construction for extra strength
- Compatible with diesel and gasoline
- Includes a fuel sender for gauge hookup
Pros: Very rugged build; Versatile fuel compatibility
Cons: Heavy and may require two people to install
5. Koller Engineering 30 Gallon Aluminum Fuel Tank: Lightweight
The Koller Engineering 30 gallon aluminum fuel tank is designed for those who want to maximize payload capacity. Its low profile allows it to fit under most tonneau covers, and the aluminum construction keeps weight down. Based on owner feedback, installation is straightforward, and the tank is leak-free when properly mounted.
However, aluminum is more prone to dents and damage from impact compared to steel. Some users also reported that the included filler neck was not long enough for their truck bed configuration. If you need a lightweight tank for occasional use and have a covered bed, this could work, but for heavy off-road use, a steel tank might be better.
- Lightweight aluminum saves payload
- Low profile design fits under tonneau covers
- Includes a filler neck and cap
Pros: Easy to handle due to low weight; Space-saving shape
Cons: Aluminum can dent more easily than steel
6. Dee Zee 30 Gallon Diesel Fuel Tank: Budget Friendly
The Dee Zee 30 gallon diesel fuel tank is an entry-level option for those on a tight budget. It is made from polyethylene and includes a 12V pump, making it a ready-to-use solution. Owner feedback indicates it works well for occasional fueling needs and is easy to install.
However, the plastic construction has limitations: it can warp if left in direct sunlight for extended periods, and some users reported leaks around the pump fittings over time. It is also only recommended for diesel, not gasoline. If you need a temporary or low-cost setup for diesel, this tank is acceptable, but for long-term reliability, invest in a metal tank.
- Rotomolded polyethylene resists rust
- Includes a 12V pump and nozzle
- Low price point
Pros: Very affordable; Complete kit with pump
Cons: Plastic may warp in high heat
7. Go Rhino 30 Gallon Steel Fuel Tank: Rugged Build
The Go Rhino 30 gallon steel fuel tank is a no-frills option for those who want a rugged tank without extra components. The steel is heavy-gauge and powder coated for corrosion resistance. It comes with mounting hardware, making installation straightforward. Owner feedback notes that it is very solid once mounted.
However, this tank does not include a fuel sender or pump, so you will need to purchase those separately. The lack of internal baffles can lead to fuel slosh. If you already have a pump and gauge system and want a basic, durable tank, this could work, but it may not be the best value for most buyers.
- Heavy-gauge steel with black powder coat
- Includes mounting brackets and straps
- Compatible with diesel and gasoline
Pros: Sturdy construction; Good corrosion resistance with powder coat
Cons: Lacks a fuel sender or pump
Frequently Asked Questions
Are 30 gallon fuel tanks legal for on-road use?
In most states, it is legal to carry fuel in an auxiliary tank in the bed of a truck, but you must comply with specific regulations. The tank must be securely fastened, have proper venting, and not exceed the vehicle’s gross vehicle weight rating (GVWR). Some states require the tank to be UL listed or meet similar safety standards. Always check your local laws before installing.
Can I use a 30 gallon fuel tank for gasoline?
Yes, but only if the tank is rated for gasoline. Steel and aluminum tanks are generally safe for gasoline, while polyethylene tanks may not be suitable due to fuel permeation. Always check the manufacturer’s specifications. Additionally, gasoline vapors are more volatile, so proper venting and grounding are critical to prevent fire hazards.
How do I install a 30 gallon fuel tank in my truck bed?
Installation typically involves placing the tank in the bed, securing it with the provided brackets or straps, and connecting the fuel line to your engine or a transfer pump. Most tanks require drilling holes for mounting, but some use existing bed tie-downs. Ensure the tank is level and does not interfere with bed access. Always follow the manufacturer’s instructions and consider professional installation if you are not experienced.
Do I need a pump to transfer fuel from the tank?
Most 30 gallon tanks do not include a pump, though some do. If you plan to use the tank as a reserve fuel supply, you will need a 12V electric pump or a manual hand pump to transfer fuel to your vehicle’s main tank. Some tanks are designed for gravity feed, but this is less common for in-bed tanks. Check the product specifications before purchasing.
How do I prevent fuel theft from a bed-mounted tank?
To deter theft, choose a tank with a lockable fuel cap. Additionally, you can install a locking fuel door or use a security cable around the tank. Parking in well-lit areas and using a bed cover can also help. Some tanks have a locking mechanism integrated into the filler neck, which adds an extra layer of security.
