Understanding the Types of Auxiliary Fuel Tanks
Auxiliary fuel tanks come in various configurations, each suited for different needs and applications. It’s crucial to understand the distinction between them.
-
Transfer Tanks (Non-Plumbed):
- Purpose: Primarily designed for transferring fuel from the tank to other vehicles, machinery, or equipment (e.g., ATVs, generators, tractors). They are not plumbed directly into the truck’s main fuel system.
- Operation: Fuel is dispensed using a hand pump, a 12V electric pump, or a gravity feed system (if the tank is elevated).
- Common Use: Construction sites, farms, recreational use where equipment needs fueling, or simply carrying extra fuel for emergency situations.
- Shapes/Mounting: Often L-shaped or rectangular, designed to fit snugly in the truck bed. Some integrate with a toolbox.
- Legal Note: Generally fewer regulations than plumbed tanks, but still subject to capacity limits and hazmat rules for transport.
-
Auxiliary Fuel Tanks (Plumbed/Gravity Feed/Pumped):
- Purpose: Designed to directly supply fuel to the truck’s main fuel system, extending its driving range.
- Operation:
- Gravity Feed: The auxiliary tank is mounted higher than the main tank, allowing fuel to flow by gravity. A valve (manual or electric) controls the flow. Simple but requires careful monitoring to prevent overfilling the main tank.
- Pump-Driven (with Electronic Switching): A fuel pump within the auxiliary tank transfers fuel to the main tank. An electronic control system manages the transfer, often automatically topping off the main tank when it reaches a certain level, or allowing manual transfer at the flick of a switch. This is the most sophisticated and often preferred method for true range extension.
- Common Use: Long-haul towing, commercial fleets, overlanding, or any scenario where continuous, extended driving range is desired.
- Legal Note: These tanks are subject to more stringent regulations (e.g., DOT, EPA, state-specific laws) regarding installation, venting, and fuel type compatibility due to their direct connection to the vehicle’s fuel system.
Key Considerations Before Purchasing and Installing
Choosing the right auxiliary fuel tank requires careful thought. Here are the critical factors to evaluate:
- Capacity: How much extra fuel do you genuinely need? Tanks range from 30 gallons to over 100 gallons. Consider your typical trips, fuel consumption, and desired range. Remember that fuel adds significant weight (diesel ~7 lbs/gallon, gasoline ~6 lbs/gallon), impacting your truck’s payload capacity.
- Material:
- Aluminum: Lightweight, corrosion-resistant, often more expensive. Excellent for all fuel types (ensure proper internal coatings for gasoline).
- Steel: Durable, robust, heavier, and generally more affordable. Requires internal and external coatings to prevent rust, especially for gasoline.
- Polyethylene (Plastic): Lightest, most affordable, and naturally corrosion-resistant. Primarily used for diesel or DEF (Diesel Exhaust Fluid) due to material compatibility with gasoline.
- Fuel Type Compatibility: Crucially important! Ensure the tank is explicitly rated for the type of fuel you intend to carry (diesel, gasoline, or DEF). Using a tank not designed for gasoline can be extremely dangerous due to material degradation, static electricity, and fire risk.
- Mounting Location:
- In-Bed: Most common, tanks sit directly in the truck bed, often consuming bed space. Many are designed to fit around wheel wells or in L-shaped configurations.
- Under-Bed/Frame Mounted: Less common for standard pickups, more for commercial chassis or custom builds, as it requires significant modification and professional installation. It frees up bed space.
- Toolbox Combo: Combines a transfer tank with a functional toolbox, saving space and offering dual utility.
- Installation Method: While some transfer tanks can be installed by a competent DIYer, plumbed auxiliary tanks, especially those with electronic switching, are complex and involve working with fuel lines and electrical systems. Professional installation is highly recommended for plumbed systems to ensure safety, compliance, and proper functionality.
- Legal & Safety Regulations: This cannot be overstressed. Research federal (DOT, EPA) and state/local regulations regarding fuel transport, tank construction, venting, and spill prevention. Proper grounding, pressure relief, and shut-off valves are not just features; they are safety requirements.
- Vehicle Compatibility: Measure your truck bed dimensions carefully. Consider your truck’s Gross Vehicle Weight Rating (GVWR) and payload capacity. Adding 100 gallons of fuel adds 600-700 lbs, plus the weight of the tank itself.
