Auxiliary Fuel Tank
& Toolbox Combo Installation
Professional auxiliary fuel tank, transfer tank, and fuel-tank/toolbox combination installation for compatible pickup trucks, work trucks, service vehicles, and other eligible applications. Torklift Central can review tank capacity, toolbox storage, bed fitment, vehicle payload, fuel type, transfer-only or auxiliary-feed configuration, mounting hardware, pumps, wiring, hoses, fittings, venting, filler access, and towing-equipment clearance before recommending an installation path.
Why Fuel Tank & Toolbox Combo Installation Starts With Fitment
An auxiliary fuel tank or tank-and-toolbox combination needs more than enough bed space. Truck configuration, bed dimensions, available payload, fuel type, approved product use, tank capacity, toolbox size, filler access, venting, pump or gravity-feed design, plumbing, electrical requirements, bedliner, tonneau cover, fifth-wheel or gooseneck hitch clearance, and intended use all affect the installation. A complete application review helps determine whether the selected system is appropriate.
- Tank & Truck Fitment Bed size, rail dimensions, cab clearance, mounting locations, filler access, and the selected tank or combo-unit dimensions are reviewed together.
- Payload Awareness The empty tank, fuel, toolbox contents, passengers, cargo, hitch equipment, and other accessories all count toward the truck's available capacity.
- Fuel-System Review Fuel type, tank approval, transfer-only versus auxiliary-feed use, pump, hoses, fittings, valves, venting, and routing are reviewed before installation.
- Electrical & Pump Setup When applicable, pumps, switches, controllers, wiring, grounding, weather protection, and circuit protection are matched to the confirmed system.
- Toolbox & Towing Clearance Toolbox lid movement, tonneau hardware, hitch equipment, trailer clearance, bed access, and nearby components are considered before mounting.
Not every tank, transfer system, toolbox combo, universal mounting kit, or fuel-feed component is suitable for every truck or fuel type. Final recommendations depend on inspection, manufacturer instructions, product condition, fuel compatibility, payload, mounting access, plumbing and electrical requirements, parts availability, existing modifications, and intended use.
Professional Auxiliary Fuel Tank & Toolbox Combo Installation Process
Auxiliary fuel tank and toolbox combo installation is vehicle-, product-, and fuel-specific. Our team reviews the truck, bed dimensions, payload, fuel type, tank or combo-unit design, intended fuel use, mounting system, pump, wiring, hoses, fittings, venting, filler access, tonneau or towing equipment, and product instructions before recommending an installation plan.
Truck & Application Review
We review the truck, bed size, available payload, current accessories, towing equipment, intended fuel use, selected product, and existing modifications.
Tank & System Fitment
We confirm dimensions, capacity, fuel compatibility, approved use, mounting points, toolbox and filler access, pump, plumbing, wiring, venting, and clearances.
Mounting & Connections
When approved, the tank or combo unit, brackets, fasteners, pump, wiring, hoses, fittings, valves, venting, and related components are installed for the confirmed application.
Final Review
We review mounting security, toolbox and filler operation, accessible connections, wiring and pump function where applicable, clearances, and follow-up guidance.
Quoted Installation Time: Actual installation time may vary based on truck configuration, tank or combo-unit type, mounting access, fuel-system design, pump, wiring, plumbing, venting, drilling, fabrication, bedliner, tonneau or hitch equipment, corrosion, missing hardware, parts, and installation scope.
Fuel Tank, Toolbox & Transfer-System Components We Can Review
Torklift Central can review common auxiliary fuel tank, transfer tank, and tank-and-toolbox combination configurations and recommend an installation path after the truck and selected product are evaluated. The correct setup depends on vehicle fitment, payload, fuel type, product approval, tank dimensions, mounting points, plumbing, electrical needs, clearances, included components, and intended use.
Some Tank-And-Toolbox Applications Need More Than The Included Hardware
Work trucks, service bodies, flatbeds, modified beds, heavy combination units, and unusual accessory layouts may require additional brackets or fabrication. We can review whether a secure custom mounting solution is practical for the truck, loaded system, and intended use.

Fuel Tank & Toolbox Combo Installation For Common Truck Applications
Torklift Central can review auxiliary fuel tank, transfer tank, and tank-and-toolbox combination installation for many compatible pickup trucks, work trucks, service vehicles, flatbeds, utility bodies, fleet vehicles, towing vehicles, and other eligible applications. The correct system depends on the exact truck, bed dimensions, vehicle payload, fuel type, tank approval and intended use, transfer-only or auxiliary-feed configuration, tank and toolbox dimensions, filler access, venting, pump, wiring, hoses, fittings, mounting design, tonneau cover, fifth-wheel or gooseneck hitch, trailer clearance, existing modifications, parts availability, and product instructions. Not every tank, pump, feed system, or universal mounting kit fits every truck or fuel type.
Why Choose Torklift Central For Auxiliary Fuel Tank & Toolbox Combo Installation?
Fuel tank and toolbox combo installation can involve payload review, bed and rail fitment, drilling, heavy mounting systems, isolation between materials, pump and electrical setup, hoses, fittings, venting, filler access, tonneau or hitch clearance, toolbox operation, custom fabrication, and nearby component conflicts. Torklift Central brings decades of towing, fabrication, work-truck, vehicle-upfit, and accessory-installation experience to help review the complete application rather than treating every fuel tank as a universal fit.

Our Auxiliary Fuel Tank & Toolbox Combo Recommendations
Our recommended starting point is selecting a tank or combination unit documented for the intended fuel, application, and installation method, then confirming the truck's bed dimensions, available payload, current accessories, and towing configuration. A dimensionally confirmed, application-appropriate system is usually the cleanest starting point, while work trucks, service bodies, flatbeds, towing applications, and modified beds may require heavier mounting hardware, additional plumbing or wiring, or custom fitment review.
Auxiliary Tank & Toolbox Combo Systems
For drivers who need both additional fuel capacity and secure storage, we recommend a combination unit with confirmed truck-bed fitment, payload allowance, fuel compatibility, approved use, filler access, toolbox operation, mounting instructions, and sufficient clearance from tonneau and towing equipment.
Best for:
- Pickup trucks with confirmed bed dimensions and available payload
- Owners who need fuel capacity and lockable tool storage together
- Applications with documented fuel and installation compatibility
- Trucks with sufficient filler, lid, cab, and towing-equipment clearance

Frequently Asked Questions
Do you install auxiliary fuel tank and toolbox combination units?
Yes. Torklift Central can review and install compatible auxiliary fuel tank and toolbox combination units on eligible pickup trucks, work trucks, service vehicles, and other applications. Installation depends on the exact truck, bed dimensions, vehicle payload, fuel type, product design, mounting system, plumbing or transfer method, electrical requirements, clearances, and intended use.
What is the difference between an auxiliary fuel tank and a transfer tank?
An auxiliary tank may be designed to supply fuel to the vehicle through an approved system, while a transfer tank is generally used to move fuel to other equipment through a pump and hose. The product instructions and approved use must be confirmed before installation because not every tank is designed to connect to a vehicle fuel system.
Can you install a fuel tank and toolbox combo with a tonneau cover?
Some combinations may work together, while others conflict with tonneau rails, canisters, hinges, latches, or the opening path. The truck bed, cover system, tank-and-toolbox dimensions, filler access, lid movement, and mounting method should be reviewed before installation.
Can a fuel tank toolbox combo be installed with a fifth-wheel or gooseneck hitch?
It may be possible when there is sufficient clearance for the hitch, trailer movement, fuel fittings, toolbox lid, filler access, and bed use. Tank height and depth, hitch position, trailer clearance, plumbing, and the complete towing setup must be reviewed before installation.
Can you install a customer-supplied tank or toolbox combo?
Customer-supplied systems may be considered after the product, truck fitment, fuel compatibility, condition, instructions, mounting method, included hardware, pump, wiring, hoses, fittings, venting, and intended use are reviewed. Missing, damaged, incompatible, or unapproved components may need to be replaced before installation.
Do you install pumps, wiring, hoses, and fittings?
Depending on the system, installation may include an approved pump, switch or controller, wiring, circuit protection, grounding, hoses, fittings, valves, venting, and secure routing. The exact components depend on the tank type, fuel type, product instructions, vehicle configuration, and intended use.
Can any auxiliary tank be used for gasoline or diesel?
No. The tank, pump, hoses, fittings, seals, venting, and related components must be approved for the specific fuel and intended application. A product should not be installed for a fuel type or use that is not supported by its manufacturer instructions.
Will installation require drilling or custom brackets?
Some systems use supplied brackets or existing attachment points, while others may require drilling or additional fabrication. The mounting method depends on the truck, bed structure, tank-and-toolbox design, product instructions, available attachment points, loaded weight, and intended use.
How much does auxiliary fuel tank and toolbox combo installation cost?
Pricing is inspection- and application-based. Final pricing depends on the truck, selected tank or combo unit, mounting system, fuel type, pump, wiring, hoses, fittings, venting, drilling, fabrication, bedliner, tonneau or hitch clearance, access, corrosion, existing modifications, parts, labor, and installation scope.
Does an auxiliary fuel tank increase the truck's payload rating?
No. The tank, toolbox, fuel, tools, cargo, passengers, hitch equipment, and other installed accessories all add weight and do not increase the truck's GVWR, payload, axle, tire, wheel, or other manufacturer ratings. Available payload should be reviewed before selecting a tank capacity or combination unit.
