Capacity and construction: 45 gallons. RDS emphasizes a full range of tanks and states gasoline auxiliary fueling is allowed when siphoned from the top with an electric pump. Fully welded seams contribute to durability and long life in rugged environments.
RDS MFG INC Fuel Tank – 60-Gallon
Capacity and notes: 60 gallons. The range includes multiple capacities to suit different bed lengths and vehicle types. The product notes indicate gasoline auxiliary fueling is allowed via top-siphoning with an electric pump, and one should measure bed compatibility before ordering.
DEE ZEE DZ91753 Aluminum Auxiliary Tank
Capacity and construction: 106 gallons. This rectangle transfer tank uses non-rusting 0.125 Brite-Tread aluminum and features a radius curve to minimize weld pressure points. It includes a cap and coupler for venting, supporting reliable operation in extended fueling scenarios while maintaining structural integrity.
Buying Guide: Key Purchase Considerations And Comparisons
- Capacity needs: Choose a tank size that aligns with average trip duration, vehicle load, and fueling frequency. Large capacities (e.g., 200 gallons) are suitable for long-range use, while smaller tanks (30–60 gallons) fit compact spaces.
- Material and durability: Aluminum tanks are corrosion-resistant and lighter than steel. Look for fully welded seams and reinforced mounting brackets to support rugged conditions.
- Slosh reduction: Tanks with baffled designs minimize fuel movement and improve stability on rough roads. Baffles are especially beneficial for larger capacities.
- Installation compatibility: Verify bed length, mounting provisions, and existing frame clearance. Some tanks are better suited for short-bed pickups, while others fit broader vehicle types.
- Access and maintenance: Features like sight gauges, clean-out ports, venting caps, and accessible fill/vent connections simplify routine checks and service.
- Fuel type compatibility: Most are designed for gasoline or diesel with specific top-siphon and electric pump configurations. Confirm compatibility with your intended fuel and equipment.
- Warranty and support: Consider manufacturer warranties and the availability of replacement fittings or parts for long-term reliability.
- Cost vs. value: Higher-capacity or specialized tanks may cost more upfront but can reduce refueling stops and improve logistics for fleets or frequent travelers.
Across these options, buyers should assess overall height, width, and length to fit undercarriage space, alongside weight limits for trailer or truck frames. Consider how the tank integrates with existing fuel lines, pumps, and accessories to ensure a seamless upgrade that meets safety standards and local regulations.
