CUCNEXT portable fuel tank 5L (1.3 gal) Black — Locking cap & upgraded 1" tube bracket, HDPE

This 1.3-gallon (5L) auxiliary tank combines rugged HDPE construction with a keyed lock and a reinforced bracket system so you can carry extra fuel securely during rides, work days, or emergency trips. The package includes a locking cap, an ergonomic carry handle and hardware compatible with 1" U-bolt mounting, offering a balance of safety, portability and easy installation for a variety of vehicles.

How secure is the locking and mounting system?

The tank uses a keyed lock on the fill cap to deter tampering and accidental openings in transit. An upgraded bracket and robust fastening system keep the tank fixed to 1" tube frames, minimizing wobble during off-road or highway use.

• Keyed locking cap prevents unauthorized access and fuel spillage.
• Reinforced bracket engineered for 1" tube with U-bolt attachment.
• Heavy-duty fasteners reduce movement and vibration under load.

What materials and durability features does the tank offer?

Constructed from high-density polyethylene (HDPE), the tank resists impacts, UV exposure and corrosion better than thin metal alternatives. Its molded shape and thick walls provide structural strength while keeping weight low for easier handling.

• HDPE body resists dents, rust and chemical degradation.
• Robust molded handle for comfortable carrying and lifting.
• Fade-resistant black finish suited to outdoor conditions.

How easy is it to install and use on different vehicles?

The included upgraded bracket and U-bolt are tailored for 1" tubing, common on motorcycle frames, roll cages, luggage racks and many ATV/UTV bars. Installation is straightforward with basic hand tools, and the tank’s light weight makes mounting and removal manageable for one person.

• Mounting hardware included for quick attachment to 1" tubes.
• Ergonomic handle aids lifting and quick detachment.
• Simple fill cap operation with key lock for everyday use.

What capacity and usability should I expect on trips?

At 5 liters (1.3 gallons), the tank provides a useful reserve for short detours, remote work sites or as a safety backup on long rides. It’s sized to add range without adding excessive bulk, and the design balances fuel volume with portability and mounting options.

• 1.3 gallon/5L capacity for emergency top-ups or extended range.
• Compact footprint fits small luggage spaces and rack-mounted setups.
• Lightweight for carrying when detached from the vehicle.

Who is this for: Riders, outdoor workers and vehicle owners who need a compact, secure auxiliary fuel container that mounts to 1" tubes. If you want a durable, lockable reserve tank that’s easy to mount on motorcycles, ATVs, UTVs, SUVs or custom racks—CUCNEXT’s 5L portable tank is built for practical, everyday use without complicated installation or heavy weight.
