Western Global FCP250: Double-Walled Fuel Cube Stationary Tank
The Western Global FCP250 is a stationary double-walled gasoline storage tank designed for secure, everyday fuel transfer. It includes a 115V, 12 GPM pump kit and a fuel level gauge, with a lockable equipment cabinet to contain ports and equipment. The design supports spill containment via 110% containment and UL 142 approval, reducing the need for separate spill pans. An emergency vent kit aids safe gasoline usage, and the cabinet can be stacked two high when empty to save space in storage areas.
Western Global FCP500: Double-Walled FuelCube Stationary Tank
The FCP500 extends the features of the FCP250 into a larger 544 US gallon capacity while maintaining double-walled containment. The lockable cabinet, 115V/12 GPM pump kit, and fuel level gauge continue to support secure fueling operations. Like the smaller model, it offers 110% containment, UL 142 approval, and an emergency vent kit suitable for gasoline. It’s designed to minimize storage footprint when stacked, helping fleets optimize space in tight environments.
Smart Oil Gauge Adapter for Roth and Granby Double-Walled Tanks
This adapter provides high compatibility with Roth 400L, 620L, 1000L, and 1000LH double-wall tanks. It uses machined aluminum and an internal guide cone to ensure accurate oil level readings by allowing the Smart Oil Gauge to see directly down to the level. Installation is straightforward without special tools, making it suitable for both professionals and do-it-yourself setups.
TITAN Fuel Tanks 7020217 XXL Replacement Diesel Tank
The TITAN 7020217 XXL is a midship, cross-linked polyethylene tank designed as a 55 gallon replacement option for Ford F-250/F-350 apps. It emphasizes compatibility with stock OE sending units and supports use with common aftermarket brands. While not double-walled, its durable construction and ample capacity make it a practical choice for upgrading tank size in trucks without compromising core systems like steps or airbags.
Scepter Rectangular 12 Gallon Marine Fuel Tank
Designed for outboard boats, this 12 gallon Scepter tank focuses on durability and reduced evaporation. The rugged one-piece shell minimizes fuel loss and preserves octane value. Its integrated molded hand holds aid transport, while the compact size supports longer running times for small vessels. While not double-walled, it remains a popular choice for portable marine fueling in tight spaces.
attwood 6-Gallon Portable Marine Tank With Gauge
Attwood’s 6-gallon portable marine tank combines EPA/CARB compliance with a built-in gauge and automatic vacuum valve option to promote proper fueling flow and minimize emissions. Its compact size makes it ideal for auxiliary fueling on boats or as a secondary tank in small craft. The design supports efficient transfer with reduced fuel evaporation and improved control over the fueling process.
Buying Guide: Key Purchase Considerations
- Containment and safety: Double-walled designs provide 110% containment for gasoline and diesel, lowering spill risk. Verify UL or equivalent approvals for your application and environment.
- Security and accessibility: Look for lockable cabinets or secure access to ports to prevent tampering while enabling controlled fueling in busy workplaces.
- Capacity and footprint: Choose tank size based on usage and available space. Stationary tanks benefit from stackable designs in tight storage areas, while portable tanks prioritize weight and portability.
- Pump and gauge integration: Built-in pumps and level gauges streamline fueling operations and monitoring. Ensure compatibility with existing pumps (e.g., 12 GPM) and electrical requirements (115V, etc.).
- Material and compatibility: Double-walled tanks are common in UL-rated configurations, while some models use cross-linked polyethylene. Confirm compatibility with your fuel type and vehicle or equipment.
- Mobility vs. permanence: Stationary tanks suit fixed fueling stations and fleets; portable tanks suit boats and remote sites. Consider environmental exposure and mounting needs when selecting.
- Maintenance and venting: Emergency vent kits and appropriate venting reduce vapor buildup and enhance safety during transfers and storage.
