How to Securely Mount Gas Cans on Your Vehicle

Proper mounting is the most critical factor in preventing fuel container failure. Always use purpose-built, vibration-dampening cradles rather than relying solely on bungee cords or generic ratchet straps. Ensure the container is mounted in a location that avoids direct, prolonged sunlight to minimize internal pressure buildup and UV-induced material fatigue.

When mounting to a vehicle exterior, consider the impact on the center of gravity and handling. Placing heavy fuel loads high on a roof rack increases body roll and vehicle instability on uneven terrain. Wherever possible, mount fuel cans low and centered between the axles to maintain predictable handling during technical off-road driving.

• Roof Mounts: Best for space management but requires low-profile, aerodynamic brackets.
• Rear Bumper/Swing-out: Excellent for accessibility and keeping weight lower, but increases departure angles.
• Internal/Bed Mounts: Safest from impact and UV, but requires ventilation to manage fumes.

Managing Fuel Expansion in Extreme Temperatures

Liquid fuel expands significantly when temperatures rise, a reality that catches many adventurers off guard. Always leave adequate “headspace”—a small air gap at the top of the container—to allow for this expansion. Never fill a container to the brim, especially if transferring fuel in the cool of the morning, as the afternoon sun will cause the contents to pressurize the container walls.

In high-altitude or high-heat environments, the pressure differential can lead to bulging or even failed seals. Periodically “burp” the container by carefully loosening the cap in a shaded area to release built-up vapor pressure. If a container shows signs of extreme distortion, move it to a cooler location immediately and monitor the seals for potential seepage.

CARB Compliance and Long-Term Container Care

California Air Resources Board (CARB) compliance mandates specific nozzle designs intended to reduce evaporative emissions. While these nozzles are mandatory in certain regions, many find them difficult to use in the field. Always inspect the seals and O-rings of your CARB-compliant nozzle during your pre-trip maintenance check, as these complex parts are the most likely to fail or clog.

For long-term care, store all fuel containers in a cool, dry place away from direct sunlight when not in use. Clean the exterior of plastic cans with mild soap and water to prevent dirt and road grime from wearing down the finish. Periodically flush the interior of the can if you notice sediment or debris buildup to ensure the fuel remains clean for your vehicle’s sensitive fuel system.

Properly outfitting your rig with reliable fuel storage removes a significant layer of stress from any backcountry expedition. Whether you choose the rugged simplicity of steel or the tactical flexibility of modern polymers, the best gear is the one that allows you to focus on the trail ahead. Keep your containers well-maintained, mount them securely, and prioritize safety so you can explore further with total confidence.
