Auxiliary Fuel System

Expand Your Range with Confidence
For truck owners, overlanders, and fleet operators who demand extended driving range without compromising cargo space or safety, our Auxiliary Fuel System category offers purpose-built solutions. Whether you’re hauling equipment across remote job sites, towing a heavy trailer, or embarking on cross-country adventures, these systems allow you to carry additional diesel safely and efficiently. Designed to integrate seamlessly with existing fuel infrastructure, each product in this collection prioritizes durability, ease of installation, and reliable fuel delivery—so you stay on the road longer, with fewer stops.

What to Look For
When selecting an Auxiliary Fuel System, consider the following factors to ensure a perfect match for your vehicle and usage:

Vehicle Compatibility: Verify that the system is designed for your specific make and model, including mounting points and fuel line connections. Many kits are vehicle-specific to avoid modification headaches.
Installation Complexity: Look for kits that include all necessary hardware, brackets, and clear instructions. Some systems are plug-and-play, while others may require professional installation.
Fuel Transfer Method: Decide between gravity-fed, pump-assisted, or automated transfer systems. Pump-based options offer faster, more controlled refueling, especially for larger tanks.
Build Quality & Safety: Prioritize systems with heavy-duty materials, leak-proof fittings, and certifications (e.g., CARB or EPA compliance) to ensure safe operation under vibration and temperature extremes.
Capacity vs. Space: Balance fuel capacity with the physical footprint. Compact designs that fit in truck beds, underbody mounts, or spare tire locations preserve usable cargo area.
