For on-site fueling needs, selecting a durable gas or diesel tank designed to fit in a truck bed is essential. This guide highlights reliable, weather-resistant fuel cells and portable transfer tanks that maximize capacity, portability, and safety. Each option is evaluated for material quality, ease of installation, and compatibility with common fuels.
| Product | Capacity | Material | Notable Feature |
|---|---|---|---|
| EVIL ENERGY 19 Gallon Fuel Cell | 19 gal | Aluminum | Built-in level sender |
| AM-TANK 58 Gal Portable Tank | 58 gal | Polyethylene | Lockable latches and forklift pockets |
| AM-TANK 116 Gal Portable Tank | 116 gal | Polyethylene | Designed for on-site diesel transfer |
| RANZHIX 17 Gallon Rectangular Tank | 17 gal | Aluminum | 8 AN fittings with multi-use potential |
| ExploreHorizon 48 Gallon with Pump | 48 gal | Polyethylene | 12V pump, 10 GPM |
Across these options, buyers should consider compatibility with their vehicle and fuel type, the presence of a level sender for monitoring, portability features for loading and unloading, and the durability of the tank against weather and road debris. The following product sections provide concise details to aid decision-making.
EVIL ENERGY 19 Gallon Aluminum Fuel Cell

The EVIL ENERGY 19-gallon fuel cell is constructed from aluminum and features a built-in 3–90 ohm level sensor with internal anti-slosh foam. Its dimensions are approximately 29.5 inches long, 12 inches wide, and 12 inches high, with 8AN inlet/outlet fittings. This unit supports multiple fuels, including gasoline, diesel, methanol, water, and ethanol, though it is not recommended for E85 gasoline when paired with CPE fuel lines. The compact size makes it suitable for bed-mounted transport or slide-in compartments, while the included level sensor helps monitor remaining fuel without frequent manual checks.
AM-TANK 58 Gallon Portable Tank

This 58-gallon portable tank provides a balance of capacity and portability for on-site fueling. It uses durable roto-molded polyethylene and includes an integrated cover lid to protect contents from weather and sun. Security is enhanced with lockable latches, and the design incorporates forklift pockets and ergonomic handles for easier transport, whether the tank is full or empty. This option is well-suited for crews needing reliable fueling on job sites where a compact footprint is important.
AM-TANK 116 Gallon Portable Tank

The 116-gallon AM-TANK fuel container is designed primarily for diesel transfer on-site. It shares the rugged roto-molded polyethylene construction with an integrated weather shielded lid, ensuring durability under harsh conditions. Like the 58-gallon model, it features forklift pockets and secure transport recesses to simplify loading, unloading, and stable transit, whether full or empty. This size suits larger work fleets or longer fueling runs between refueling stops.
RANZHIX 17 Gallon Rectangular Tank

The RANZHIX 17-gallon rectangular tank uses aluminum for reduced weight while maintaining sturdiness. It features 8 AN fittings, a 0-90 ohm fuel transmitter, and a top-feed design with a flip vent. Its dimensions are 30″ x 17″ x 7″ (LXWXH). The unit is touted as easy to install and maintain and is described as multi-functional: suitable for storing not only fuel but also other gases in some configurations. This makes it a flexible option for enthusiasts who want a compact but capable bed-mounted fuel cell or auxiliary tank.
ExploreHorizon 48 Gallon Portable Fuel Tank With Pump

This 48-gallon portable fuel tank features a 12V electric pump delivering up to 10 GPM, along with a 13-foot hose and auto nozzle. The heavy-duty polyethylene body resists dents, rust, and corrosion and is designed to withstand varying weather conditions. It is a practical choice for quick on-site refueling across trucks, tractors, boats, and generators. The built-in pump reduces manual handling time and provides efficient transfer for busy work environments.
Buying Guide: Key Purchase Considerations
Choosing the right bed-mounted fuel tank or portable transfer tank depends on several factors. First, assess capacity needs: smaller 17–19 gallon cells are more compact for tight bed spaces, while 58–116 gallon options suit longer fueling cycles or higher-demand fleets. Material choice matters: aluminum offers lightness and corrosion resistance, whereas high-density polyethylene provides rugged durability and weather resistance at a lower weight. Inlet/outlet configurations, such as 8AN versus 10AN fittings, affect compatibility with hoses and pumps already on site. A built-in fuel level sender helps with monitoring without manual gauging, a feature found on several EVIL ENERGY models. For mobile use and transport, look for features like forklift pockets, locking lids, and built-in anti-spill or anti-slosh foam that reduce fuel loss during movement. Finally, consider installation practicality: some tanks are designed for simple bed mounting, while others are better suited for wall or frame mounts or temporary job-site setups. Always verify compatibility with your vehicle’s bed dimensions and ensure that the chosen fuel type aligns with the tank’s stated application. For mixed-use scenarios where multiple fuels are stored, confirm line compatibility and seal integrity to minimize cross-contamination risk.
