From remote construction sites in the Rockies to mining operations and alpine agriculture, working in Colorado’s high-altitude terrain demands equipment that can perform in extreme conditions. Fuel storage is no exception. Temperature swings, thin air, and steep terrain can create pressure-related issues and affect the performance and safety of your fuel system.
This guide explores the best types of fuel tanks for high-altitude operations and how to ensure reliable, compliant storage in Colorado’s mountainous regions.
The Challenges of Fuel Storage at High Altitudes
Fuel storage in Colorado’s mountain zones faces several unique challenges:
- Rapid temperature fluctuations between day and night
- Increased vapor pressure due to lower atmospheric pressure
- Fuel expansion and contraction in response to altitude and temperature
- Difficult terrain that limits placement and refueling access
- More intense UV exposure and environmental stress
These factors can lead to tank stress, vapor buildup, and even environmental risks if not properly addressed.
What to Look for in a High-Altitude Fuel Tank
The right fuel tank for high-altitude use must be engineered to handle these conditions with strength, flexibility, and safety in mind.
Pressure-Vented and Temperature-Resilient Construction
Altitude and cold can affect fuel density and vapor pressure. Look for tanks with:
-
Pressure-relief vents to accommodate vapor buildup
- Thermal expansion capabilities in the tank structure
- Reinforced welds and seams for durability
- Materials that withstand freeze-thaw cycles
Double-wall tanks offer added protection against environmental stress and leaks.
UV-Resistant Exterior Coatings
- High elevations mean stronger UV rays, which can degrade tank surfaces faster.
- Powder-coated steel or UV-stabilized poly tanks hold up best in intense sunlight
- Regular inspection of coatings and finishes helps prevent corrosion
Secure and Stable Mounting Options
Unstable ground, sloped terrain, and snowfall make tank stability critical.
- Skid-mounted tanks are ideal for rugged placement
- Anchoring hardware or built-in mounting feet help prevent movement
- Trailer-mounted systems provide mobility for remote refueling needs
Flexible Capacity for Remote Refueling
Refueling in mountain areas can be unpredictable. Tanks must be able to store enough fuel between deliveries.
- 500–1,000 gallon tanks are common for job sites and small fleets
- 2,000+ gallon tanks support larger projects or remote compounds
- Choose a size that balances accessibility with operational needs
Recommended Fuel Tank Options for Colorado’s High Country
Mills Equipment recommends the following tank types for high-altitude performance:
UL-142 Skid Tanks (500–1,000 gal)
- Steel construction with optional double-wall
- Vented for pressure changes
- Durable enough for all-season use
UL-2085 Fire-Resistant Tanks
- Added protection in forested or wildfire-prone regions
- Built-in insulation helps moderate fuel temperature shifts
- Compliant with stricter fire codes in rural areas
Poly Transport Tanks (100–300 gal)
- Lightweight, UV-resistant
- Easy to transport to remote areas by pickup or UTV
- Great for fueling equipment spread across hard-to-reach zones
Trailer-Mounted Tank Systems
- Designed for mobile use across multiple job sites
- Available with diesel, gasoline, or DEF compatibility
- Lockable, weather-sealed pump cabinets
Fuel Type Considerations at Altitude
The type of fuel in use may affect your storage strategy:
- Diesel: Prone to gelling at low temperatures—consider insulated or heated systems
- Gasoline: Requires vapor-tight storage and proper venting to manage expansion
- DEF: Must be protected from freezing (below 12°F) and direct sunlight
Mills Equipment can help configure tanks with the right insulation, accessories, and materials for your fuel type.
Compliance and Safety for Mountain Installations
High-altitude tanks must still meet EPA SPCC requirements, NFPA 30 standards, and local fire codes. Consider:
- Secondary containment for spill prevention
- Vented caps and overfill alarms
- Lockable fill points and hose compartments
Local regulations may vary by county or jurisdiction—Mills Equipment can help ensure compliance for your specific location.
