Scepter Flo ’N Go 14 Gallon Gas Caddy
The Scepter Flo ’N Go is a 53-liter portable fuel caddy designed for farm, marine, lawn, and home use. Its heavy-duty construction and 6-inch wheels enable smooth transport over rough terrain. The unit supports two fueling modes: Gravity-Flow for continuous transfer when elevated, and Manual-Pump/Siphon for controlled transfers when on the ground. The siphon mode delivers about 2.0 GPM, making it suitable for quick refueling of multiple machines. The tank’s HDPE materials resist corrosion and denting, helping extend service life in outdoor environments.
LVOUP Auxiliary Fuel Tank Install Kit
The LVOUP kit provides a high-quality aluminum and rubber assembly intended to work with gravity-fueled auxiliary tanks. It’s designed for use with a 3/8″ female pipe thread drain fitting and is compatible with 2013-2018 Dodge Ram 1500/2500/3500 models. A noted installation tip is to keep the valve closed during install to prevent fuel leakage. The kit supports a stable gravity-fed supply, helping maintain consistent fuel levels from the OE tank to auxiliary systems.
Auxiliary Fuel Tank Install Kit Diesel (1 1/2″ Fill Line)
This diesel-focused installation kit covers a broad range of vehicles from Ford, Chevy/GMC, and Dodge from 1999 to 2025. The kit includes a 1 1/2″ fill line and is positioned as a simple, corrosion-resistant solution for gravity-fed auxiliary tanks. It emphasizes compatibility with diesel engines and includes an OE part-number reference (11025) to facilitate proper part matching before purchase. Users should verify part numbers to ensure a proper fit with their vehicle’s fuel system.
LVOUP 11025 Auxiliary Fuel Tank Install Kit
This LVOUP kit mirrors diesel-focused use with aluminum and rubber components designed to prevent corrosion, offering a stable gravity-fed fuel supply from an OE tank. It supports 99-22 Ford, 11-22 Chevy/GMC, and 99-12 Dodge (diesel engines). The kit includes a note to ensure the valve remains closed during installation to minimize spillage, making it a practical choice for workshop or field use where diesel systems are involved.
Auxiliary Fuel Tank Install Kit Diesel (Diesel Focus)
This installation kit targets diesel-equipped vehicles from 1999-2025 Ford, 2011-2022 Chevy/GMC, and 1999-2012 Dodge. It features aluminum and rubber components designed to resist corrosion and provide reliable gravity-fed fuel control from the OE tank. As with similar kits, verify OEM part numbers (11025, 011025) prior to purchase to ensure compatibility with your vehicle’s system.
VEVOR Portable Diesel & Gasoline Tank
The VEVOR transfer tank is a large, 116-gallon unit designed for high-volume fueling needs. It offers a 10 GPM flow rate via a 12V pump, a 13.1-foot hose, and a front-mounted mechanical fuel gauge for capacity monitoring. A lockable upper lid adds theft protection, while the duplex filtration system helps remove large and small impurities. This option suits heavy-duty setups where frequent, rapid refueling is required for generators, tractors, or boats.
Buying Guide: Gravity Flow Fuel Tank Options
- Capacity vs. portability: Smaller caddies (like 14–15 gallons) excel for lawn tools and vehicles, while larger transfer tanks (60–116+ gallons) support longer jobs and remote sites. Consider how far you need to tow or carry the unit and whether you’ll be refilling frequently.
- Flow options: Gravity-flow is convenient when you have a raised source, but manual pumps extend reach when ground level. Devices that offer both modes provide flexibility for varied fueling scenarios.
- Materials and durability: Look for high-density polyethylene (HDPE) or corrosion-resistant aluminum/rubber components. Outdoor environments demand UV resistance, impact strength, and corrosion resistance.
- Valves, seals, and safety: Dual valves, vapor-tight seals, and anti-static grounding reduce spills and ensure safer storage of gasoline and diesel. Child-resistant caps and flame-retardant materials add safety for home settings.
- Installation kits versus standalone tanks: Install kits help convert existing tanks to gravity-fed systems, but ensure vehicle compatibility (fuel type, engine, and fill line dimensions) before purchase.
- Maintenance considerations: Filters, gaskets, and valves require periodic inspection. Check for compatibility with diesel vs. gasoline when selecting kits and hoses.
- Security and storage: Lockable lids and theft-deterrent features protect fuel, particularly in shared or remote locations. Secure mounting or stable wheels aid handling and safety.
Gravity flow fuel tank systems provide a practical solution for on-site fueling across agricultural, marine, construction, and DIY contexts. When selecting a system, balance capacity, ease of use, durability, and compatibility with your vehicle or equipment to ensure efficient and safe fueling operations.
