Buying Guide: Key Considerations For Selecting An Auxiliary Fuel Tank
- Capacity and fit: Choose a size that matches your typical distance between fuel stops and your pickup’s bed dimensions. Larger tanks offer more range but require careful mounting and space planning.
- Material and durability: Aluminum tanks resist corrosion and may be lighter, while steel tanks offer rugged strength. Consider road conditions, exposure to elements, and maintenance needs.
- Fuel type compatibility: Ensure the tank is designed for gasoline or diesel, as required by your vehicle and engine type. Some models specify compatibility with siphoning via electric pumps.
- Seams and weld quality: Fully welded seams reduce leakage risk and improve long-term durability, especially under rough-road conditions.
- Safety features: Look for overfill protection, stable baffles, drain plugs, and secure mounting options to minimize movement while driving.
- Ease of installation: Kits that include mounting brackets, hardware, and clear instructions save time and reduce fitment issues.
- Bed compatibility and clearance: Measure bed length, wheel well intrusions, and any existing fuel system components to ensure a proper fit.
- Maintenance and service: Aluminum options may need less corrosion treatment, while steel options could require rust prevention. Consider available replacement parts and pumps.
- Warranty and support: Check warranty terms and whether the manufacturer provides mounting guides or customer assistance for installation.
