1. Northern Tool + Equipment 50 Gallon Diesel Transfer Tank: Best Overall
In our evaluation, the Northern Tool 50 Gallon Diesel Transfer Tank stands out for its durable construction and reliable performance. The 14-gauge steel body with powder coating offers superior durability, and the 12V pump provides a consistent 15 GPM flow. Owner feedback highlights the ease of installation and the automatic shut-off nozzle as key benefits. However, the tank is quite heavy when empty, and moving it requires assistance.
This tank is ideal for farmers, contractors, or fleet operators who need a stationary or truck-bed mounted solution. If you need a portable tank for occasional use, consider a lighter polyethylene model instead.
- Heavy-duty 14-gauge steel construction with powder coat finish resists rust and impact.
- Integrated 12V pump delivers up to 15 gallons per minute for fast transfers.
- Includes automatic shut-off nozzle, fuel gauge, and lockable cap for safety.
Pros: Durable build and excellent corrosion resistance.; High flow rate reduces refueling time.
Cons: Heavy when full, requires two people to move empty tank.
2. Rough Country 40 Gallon Diesel Transfer Tank: Best for Trucks
Based on owner feedback and the spec sheets, the Rough Country 40 Gallon Diesel Transfer Tank is a top choice for truck owners. Its rotomolded polyethylene body is significantly lighter than steel tanks, making it easier to handle and install. The 12V pump works well for occasional transfers, though the manual nozzle can be tiring during long refueling sessions.
This tank suits those who need a portable, rust-proof option for personal use or light commercial tasks. If you require higher flow rates or automatic shut-off, consider a steel tank with a more advanced pump system.
- Compact design fits most truck beds with pre-drilled mounting holes.
- Rotomolded polyethylene construction is lightweight and impact-resistant.
- Includes a 12V pump with 12 GPM flow, hose, and manual nozzle.
Pros: Lightweight and easy to install in a truck bed.; Polyethylene tank won't rust or corrode.
Cons: Manual nozzle requires constant hand pressure; no auto shut-off.
3. Dee Zee 45 Gallon Diesel Transfer Tank: Best Heavy-Duty
We compared the Dee Zee 45 Gallon Diesel Transfer Tank against other heavy-duty models and found its 16-gauge steel with diamond plate pattern offers exceptional durability. The manual pump is reliable in remote locations but requires effort for prolonged use. Owner reviews praise its ruggedness, though some note the lack of a powered pump limits speed.
This tank is best for off-grid users, miners, or anyone who needs a tough, non-electric solution. If you prioritize convenience and speed, look for a 12V pump model.
- 16-gauge steel construction with diamond plate pattern for extra strength.
- Manual rotary pump with 8 GPM flow, no electricity needed.
- Includes a fuel gauge, lockable cap, and heavy-duty skid plate.
Pros: Extremely durable, built to withstand harsh job sites.; Manual pump works without batteries or electrical connections.
Cons: Manual pumping can be slow for large transfers.; Heavy tank, difficult to move when full.
4. Transfer Flow 30 Gallon Diesel Transfer Tank: Best Compact
In our evaluation, the Transfer Flow 30 Gallon Diesel Transfer Tank excels as a compact, lightweight option. Its aluminum body resists corrosion and keeps the tank manageable. The 12V pump delivers adequate flow for personal use, but the smaller capacity means more frequent refills. Owner feedback highlights its perfect fit under tonneau covers.
This tank is ideal for pickup owners with limited bed space or those who need a portable tank for occasional use. If you need larger capacity, consider a 50-gallon steel tank.
- Aluminum construction is lightweight and corrosion-resistant.
- Low-profile design fits under tonneau covers in short-bed trucks.
- Includes a 12V pump, hose, and fuel gauge.
Pros: Lightweight aluminum won't rust and is easy to handle.; Compact size fits in tight spaces.
Cons: Smaller capacity may not suit high-volume users.; Aluminum can dent more easily than steel.
5. RDS Manufacturing 50 Gallon Diesel Transfer Tank: Best Value
Based on owner feedback and the spec sheets, the RDS Manufacturing 50 Gallon Diesel Transfer Tank offers solid value for budget-conscious buyers. The steel build is adequate for most uses, but the powder coat may chip with heavy abuse. The pump works reliably, though a few owners experienced seal failures after a year.
This tank is suitable for occasional use on farms or job sites where cost is a primary concern. If you need a more durable pump or auto shut-off, consider spending more on a premium model.
- 14-gauge steel with powder coat finish.
- 12V pump with 12 GPM flow and manual nozzle.

However, the manual pump is less convenient than electric models, and the paint may wear over time. Owner feedback appreciates the safety focus.
This tank is best for those who prioritize safety features and don’t mind manual pumping. If you want faster transfers, choose an electric pump model.
- 14-gauge steel with safety yellow powder coat for visibility.

Frequently Asked Questions
What size diesel transfer tank do I need?
Consider your typical refueling needs and vehicle capacity. A 30-40 gallon tank is sufficient for personal use, while 50+ gallons suits commercial operations. Ensure the tank fits your truck bed or trailer space.
Should I get a manual or electric pump?
Electric pumps (12V) are faster and more convenient, ideal for frequent use. Manual pumps are reliable without power and lighter, but slower. Choose based on your transfer frequency and access to power.
Are diesel transfer tanks safe to use?
Yes, when used properly. Look for features like lockable caps, fuel gauges, automatic shut-off nozzles, and anti-siphon valves. Always ground the tank and pump to prevent static discharge, and follow manufacturer safety instructions.
Can I leave diesel in the tank for long periods?
Yes, but use a fuel stabilizer to prevent degradation. Store the tank in a dry, sheltered area to avoid moisture. Regularly check for leaks and condensation. Diesel can last up to 12 months with stabilizer.
How do I install a diesel transfer tank in my truck?
Most tanks come with mounting brackets and hardware. Secure the tank to the truck bed using bolts or straps, ensuring it does not shift. Connect the pump to the battery (if electric) and route the hose. Follow the manufacturer’s installation guide for safety.
