Looking for a reliable truck mounted gas tank to move fuel safely and efficiently? This guide highlights five top options, each chosen for different needs—whether you need portable transfer between farm equipment, a built‑in toolbox tank, or a compact under‑truck option. The best pick depends on your fuel type, capacity needs, and how you’ll transport or access the tank. Below you’ll find clear, buyer‑oriented details, plus a quick comparison table to help you decide at a glance.
| Product | Best For | Capacity | Key Benefit |
|---|---|---|---|
| 128 Gallon Portable Fuel Tank | High‑volume fueling on farms or job sites | 128 gallons | Long hose and auto shut‑off nozzle for safety |
| 60 Gallon Aluminum Transfer Tank Toolbox Combo | Truck bed use with built‑in toolbox | 60 gallons | Integrated storage and transfer capability |
| Fuel Transfer Tank, 50 Gallon | Under‑bed or portable use | 50 gallons | Compact design with robust 12V pump |
| 40 Gallon Portable Gasoline Diesel Tank | Under tonneau cover or tight spaces | 40 gallons | Low profile with detachable wheels |
| 95 Gallon Transfer Refueling Tank | DOT‑rated option for gasoline or diesel | 95 gallons | Premium capacity with transfer capability |
128 Gallon Portable Fuel Tank
Best for high‑volume fueling on farms, construction sites, or long deployments. This portable 128‑gallon unit provides plenty of capacity, a 12V 10GPM pump, auto shut‑off nozzle, and a long hose for flexible access. Choose this if you need fewer refuels and want a robust transfer setup for gasoline or diesel.
Best for truck bed or heavy‑duty use where storage and transfer must coexist. A tanker with an integrated toolbox helps keep accessories organized while allowing on‑site fueling without carrying additional containers. Be aware of the overall length and vehicle height when mounting.
60 Gallon Aluminum Transfer Tank Toolbox Combo
Best for truck beds that need both storage and a transfer capability. This combo unit combines a 60‑gallon tank with a built‑in toolbox, offering convenient organization for hoses, fittings, and accessories. Choose this if you want an integrated solution that keeps equipment secure and accessible. Limitations include potential weight and space considerations in smaller trucks.
50 Gallon Transfer Fuel Tank
Best for compact spaces where mounting under the bed or tonneau cover is preferred. This 50‑gallon transfer tank emphasizes portability with a practical 12V pump and a 13.1ft hose. Choose this if you need a versatile, under‑bed option that’s easier to maneuver and fits tighter environments. A limitation is the smaller capacity relative to larger models.
40 Gallon Portable Tank For Tight Spaces
Best for under tonneau or compact spaces where height matters. This 40‑gallon portable unit fits under most truck beds and includes detachable wheels for easier transport. It’s a practical choice when space is limited and you still need reliable fuel transfer capabilities. Note that the smaller capacity means more frequent refueling on busy sites.
95 Gallon Transfer Refueling Tank
Best for DOT‑related or regulated fueling applications. The 95‑gallon transfer refueling tank provides a larger capacity option for gasoline or diesel needs on the job site. Choose this if you require a higher volume tanker that aligns with transportation or regulatory expectations. Limitation to consider is that it may require more mounting space and handling effort than smaller units.
Buying Guide: Truck Mounted Gas Tanks
Capacity and intended use: Choose capacity based on how often you can refill and how far you travel between fueling stops. Higher capacity reduces refueling frequency but can add weight and limit vehicle load.
Mounting and space: Consider bed‑mount, under‑bed, or tonneau‑cover compatibility. Ensure there is sufficient clearance for hoses, pumps, and filler necks. The overall footprint matters for maneuvering in tight spaces.
Fuel type compatibility: Verify whether the tank supports gasoline, diesel, or both. Some models are optimized for one fuel type and may require additional adapters or safety features for multi‑fuel use.
Pump and nozzle features: Look for a robust 12V pump with a reliable flow rate (GPM) and an auto shut‑off nozzle to avoid spills. A long hose increases reach but can add clutter when parked.
Durability and safety: Materials (steel vs aluminum), corrosion resistance, and DOT or regulatory compliance affect long‑term performance and transport suitability. Safety features such as proper venting and fuel containment are important on job sites.
Accessory ecosystem: Built‑in toolboxes or integrated storage help organize hoses, fittings, and accessories. Consider whether you need extra storage for spill kits, straps, or funnels.
Mobility and maintenance: Detachable wheels and simple maintenance routines simplify moving the tank between sites. Consider cleaning access and drain options for easy upkeep.

Evaluate capacity, mounting options, fuel compatibility, and pump features. Ensure the unit fits your truck and meets safety requirements for transport and handling.
Aluminum tanks are lighter and resist corrosion, which can improve long‑term durability. Steel tanks may offer greater impact resistance in certain environments, depending on design.
Yes, it helps keep hoses, fittings, and accessories organized and secure, reducing clutter and improving on‑site efficiency.
A longer hose provides reach and flexibility, but it can add weight and susceptibility to kinking. Choose a length that matches your typical distances between the tank and dispensing point.
Auto shut‑off nozzles, secure fittings, proper venting, leak containment, and compliant materials are key safety considerations for any fuel transfer setup.
Many models are designed to handle both fuels, but verify each product’s specifications. If in doubt, select a dual‑fuel capable tank or a model clearly labeled for gasoline and diesel use.
