The JRL UAUS 2L Fuel Gas Tank is a compact replacement fuel reservoir designed to fit 49cc, 66cc and 80cc 2- and 4-stroke motorized bicycles, supplied as a complete mounting kit.

If you need a reliable fuel tank upgrade or spare for small-displacement motorized bikes, this JRL UAUS 2L tank offers a drop-in capacity with the basic hardware included. It comes with a threaded cap, an on/off fuel valve, mounting plates and fasteners so you can install it without sourcing extra parts. The tank's shape and fittings match common frame mounts on aftermarket and stock motorized bicycle setups, making it a practical swap for worn or cracked stock tanks.

Will this tank fit my 49cc, 66cc or 80cc motorized bicycle?

Yes — the UAUS 2L tank was manufactured to be compatible with the most common frame mounts and fuel connections used by 49cc, 66cc and 80cc motorized bicycle engines. Confirm the distance between your frame mounting points and the feed line thread diameter before ordering to ensure a perfect match.

• Compatible engine sizes: 49cc, 66cc, 80cc (2- and 4-stroke)
• Standard feed valve for typical fuel lines
• Mounting plates and nuts included to align with common frame brackets

What hardware comes with the fuel tank and what do I need to install it?

The package supplies the essentials to mount and connect the tank right away: cap, shutoff valve, two fixed plates and four nuts. You will need basic hand tools and may want fuel-safe hose clamps and the correct-diameter fuel hose if your existing hose doesn’t match the valve.

• Included: fuel tank, fuel cap, fuel tank switch valve, 2 fixed plates, 4 nuts
• Recommended additional items: fuel hose, hose clamps, wrench or socket set
• Installation time: typically under an hour for someone familiar with motorized bike hardware

How durable and practical is the tank for everyday use?

The UAUS tank is made for light-duty use on motorized bicycles where compact capacity and secure mounting matter more than high-volume range. With the included shutoff valve and a sealed cap, it provides reliable fuel control for casual riders and commuters using small engines.

• 2-liter capacity balances weight and ride range for small bikes
• Sealed cap and valve reduce spillage during transport or vibration
• Metal or reinforced plastic construction resists typical road wear (inspect for compatibility)

How do I maintain the fuel tank to keep my engine running smoothly?

Routine checks prevent common fuel-related problems: inspect for cracks or leaks, keep the cap seal clean, and flush the tank if you store ethanol-blended fuels for long periods. Replace the fuel line and filter as part of regular maintenance to avoid clogs and contamination reaching the carburetor.

• Visually inspect joints, seams and valve for leaks before each ride
• Use clean, fresh fuel and a fuel filter inline to protect the engine
• Drain and dry the tank if storing the bike for more than a month

Who is this for: The JRL UAUS 2L Fuel Gas Tank is aimed at riders of motorized bicycles who need a compact replacement or spare tank for 49cc–80cc 2- or 4-stroke engines. It suits hobbyists upgrading worn components, DIY mechanics building or restoring motorized bikes, and riders who prioritize a lightweight, easy-to-mount fuel solution. If you want a straightforward tank with the necessary mounting hardware included, this kit delivers the essentials for a quick installation and reliable short-range fueling.
