Best for: Tonneau-cover pickup owners.

Why it ranks #1: Its low-profile 58-gallon design is made to fit under a tonneau cover and includes a 10.5 GPM pump, 13-foot hose and automatic nozzle.

A low-profile 58-gallon tank that fits under a tonneau cover lets you carry diesel in the bed while keeping the cover closed. Its 12V pump moves fuel at 10.5 GPM through a 13-foot hose, with an automatic shut-off nozzle for refueling equipment at the worksite.

The rotomoulded antistatic polyethylene tank combines a 58-gallon capacity with a low-profile shape, making it a fit for buyers who want stored fuel concealed beneath a bed cover. The included 12V transfer unit supplies fuel at 10.5 GPM, while the 13-foot hose offers reach from the truck to equipment. An automatic shut-off nozzle and included filter are part of the dispensing setup. The pump's 30-minute duty cycle is an operating limit to keep in mind during extended refueling.

Skip it if you need to pump continuously beyond the 30-minute duty cycle; this pump is specified for timed operation.

This suits pickup owners who want a covered-bed diesel supply for tractors, excavators, generators, or trucks. The low profile is the key fit consideration, while the 30-minute pump duty cycle may constrain longer dispensing sessions.

The 40-gallon rotomoulded polyethylene tank brings a portable supply, and its 12V, 300-watt pump transfers fuel at 12 GPM for on-site dispensing. The 30-micron particulate and water separator filter is specified for cleaner diesel, while the automatic nozzle helps manage the fill at the receiving equipment. A fuel-level indicator makes inventory checks easier without relying only on estimates. The pump has a 30-minute duty cycle, and its 20-foot wire cables with clamps connect the 12V setup.

• Weight: 68.8 lb

Best for: Weather-exposed fuel haulers.

Why it ranks #4: The 58-gallon portable tank uses flame-retardant LLDPE and HDPE, and its listing states it meets DOT requirements.

A 58-gallon tank made from flame-retardant LLDPE and HDPE brings portable fuel capacity alongside stated resistance to UV, rain, snow, wear, and corrosion. CAMMOO lists a 13.2 GPM, 12V DC transfer setup, so the tank can supply fuel where equipment is working.

The 58-gallon capacity gives buyers a substantial portable supply, while the LLDPE and HDPE construction is described as suitable for outdoor use and resistant to several weather and wear factors. A 12V DC system rated at 13.2 GPM supports faster transfer than a slower-flow setup. The combo lock adds a security feature and is described as making daily access easier. CAMMOO specifies an operating range of 14°F to 104°F with fuel inside, an important boundary for seasonal use.

Skip it if you operate with fuel in the tank below 14°F or above 104°F; CAMMOO lists that range for use with fuel inside.

This is for buyers moving a 58-gallon diesel supply to outdoor work where the listed weather resistance and 13.2 GPM transfer rate matter. Keep its stated 14°F-to-104°F operating range in mind when planning use.

Why it ranks #10: This 69-gallon aluminum tank can support auxiliary fueling, but the listing describes a separate optional diesel install kit rather than a supplied pump.

The 69-gallon RDS rectangular aluminum tank is notable for its auxiliary-fueling options: diesel can gravity-feed from the bottom, while gasoline auxiliary fueling is allowed when siphoned from the top with an electric pump. Its 57-by-18-by-16-inch dimensions provide a defined footprint for planning bed placement.

The rectangular aluminum tank holds 69 gallons and measures 57 by 18 by 16 inches, giving buyers concrete dimensions for comparing it with available bed space.
