For professionals in construction, agriculture, or remote operations, having an auxiliary fuel tank mounted under the vehicle can be a game-changer. It extends range, reduces downtime, and enhances operational efficiency. This guide delves into the considerations, methods, and best practices for installing an underbody diesel transfer tank.
Understanding Underbody Diesel Transfer Tanks
An underbody diesel transfer tank is a secondary fuel reservoir installed beneath a vehicle, typically between the frame rails. It allows for refueling equipment or other vehicles without the need to return to a central fueling station. These tanks are especially beneficial for long-haul trucks, fleet vehicles, and off-road machinery operating in remote areas.
Key Considerations Before Installation
Installing an underbody diesel transfer tank is a practical solution for extending the range of your vehicle and enhancing operational efficiency. By carefully considering the tank's specifications, following proper installation procedures, and adhering to safety guidelines, you can ensure a successful and safe installation.

Key Considerations Before Installation
- Tank Capacity and Dimensions: Common sizes range from 30 to 100 gallons. Ensure the tank fits within the available underbody space without interfering with other components.
- Material: Aluminum tanks are lightweight and resistant to corrosion, making them ideal for underbody installations.
- Mounting Brackets: Use heavy-duty brackets designed for underbody mounting to ensure the tank is securely fastened and can withstand road vibrations.
- Fuel Lines and Pump: Install a 12V electric pump with appropriate hoses and nozzles. Ensure all connections are tight to prevent leaks.
- Ventilation: Proper venting is crucial to prevent pressure buildup and potential fuel spillage.
- Preparation: Lift the vehicle using a hydraulic jack and secure it with jack stands. Ensure the work area is clean and well-lit.
- Positioning the Tank: Place the tank in the desired underbody location, ensuring it doesn't obstruct any existing components.
- Marking Mounting Points: Use a marker to outline where the mounting brackets will be attached. Double-check for any obstructions before drilling.
- Drilling Holes: Drill pilot holes at the marked points, then enlarge them to fit the mounting bolts. Be cautious not to damage any underlying components.
- Mounting the Tank: Attach the mounting brackets to the vehicle's frame using bolts and nuts. Secure the tank onto the brackets.
- Installing Fuel Lines and Pump: Connect the fuel pump to the tank's outlet. Route the fuel lines to the desired dispensing location, ensuring they are secured and protected from abrasion.
- Electrical Connections: Wire the 12V pump to the vehicle's electrical system, ensuring proper fuse protection.
- Testing: Before filling the tank, test the pump operation and check for any leaks.
- Proper Ventilation: Ensure the work area is well-ventilated to disperse any fuel vapors.
- Fire Safety: Keep fire extinguishers nearby and avoid open flames during installation.
- Secure Mounting: Regularly inspect the tank and mounting brackets for signs of wear or loosening.
- Regular Inspections: Check for leaks, corrosion, and secure fittings periodically.
- Cleanliness: Keep the tank and surrounding area clean to prevent debris buildup.
- Fuel Quality: Use high-quality diesel fuel to prevent clogging of the pump and filters.
