MOTO4U 1 Liter Auxiliary Tank With Hose and Valve
The MOTO4U 1 L auxiliary tank is designed for straightforward integration with motorcycles that use a 1/4″ fuel hose interface. Its structured design helps ensure reliable connections, and the kit includes a cut-off valve and air-outlet lid to balance air pressure for smoother fuel flow. Suitable for fuel-injected bikes with external pumps as well as carbureted models, this unit is versatile enough to support refueling on certain late-model motocross bikes and compatible devices such as mowers and cars in some configurations. Capacity remains compact at 1 liter, making it a practical upgrade for riders seeking additional range without excessive weight.
Key features include: secure hose connection, compatibility with various fuel systems, an upgrade cut-off valve for precise flow control, and an air outlet in the lid to promote steady fuel delivery. This makes the 1 L auxiliary tank a pragmatic option for riders who want a lightweight boost to fuel capacity on long road or enduro trips.
AnNafi Auxiliary Fuel Tank For Servicing Bikes (300 ml)
The AnNafi 300 ml auxiliary fuel tank is tailored for workshop servicing, carb balancing, and maintenance work on bikes and other vehicles. It ships with a fuel hose, a handle/strap, and a fuel tap to ON/OFF, enabling controlled fuel delivery during servicing. Constructed for reliability, this tank supports carburetor balancing and other DIY tasks, with a 50 ml incremental level feature that helps technicians gradually add fuel for testing and tuning. Ideal for vintage to modern motorcycles that require flexible, on-hand fuel access during maintenance tasks.
MOTO4U 2 Liter Auxiliary Tank Kit
This larger-capacity 2 L auxiliary tank extends the range significantly for riders tackling long routes or trips through remote areas where fueling options are scarce. The 2 L model shares design cues with the 1 L variant, including a secure hose interface, a practical cut-off valve, and an air outlet in the lid to ensure smooth air pressure and fuel flow. It is compatible with both fuel-injected motorcycles and carbureted engines that require an auxiliary feed, and its larger capacity helps reduce fuel stops during extended rides.
Universal 1 L Auxiliary Gas Tank With Scale
This general-purpose auxiliary gas tank features a clear scale for measuring fuel, a generous filler cap for rapid refueling, and a robust 108 cm hose for flexible placement and operation. Made from ABS material, it includes a solid brass petcock control valve and is designed for reliability on long-distance rides or daily commutes. Its versatility makes it suitable for riders who value extra storage and an accurate gauge for fuel measurement during extended journeys.
Motorcycle Auxiliary Tank With Vent (500 ml)
Designed for small engine work and carburetor tuning, this 500 ml auxiliary fuel tank features a vent to support balanced air pressure during testing. It enables precise fuel delivery directly to the carburetor, which is valuable for tuning and engine testing before final assembly. The compact design makes it easy to hang on a handlebar or bench vice, reducing the risk of main tank spillage and creating a safer work environment when performing carburetor adjustments or tests on motorcycles or similar engines.
Buying Guide: Key Purchase Considerations
- Capacity needs: Choose higher capacity models like 2 L for long trips, or smaller 300–500 ml tanks for maintenance and quick refueling tests. Consider how often you ride in areas with limited fueling options.
- Compatibility: Verify hose size (1/4″ interface is common) and whether the tank supports both fuel-injected and carbureted systems. Check for external pump compatibility if applicable.
- Flow control: An adjustable cut-off valve helps manage fuel delivery, reduce spill risk, and tailor performance to specific engines or carburetors.
- Air flow design: An air outlet or vent on the lid helps balance pressure and ensures smooth fuel flow during operation and testing.
- Durability and material: ABS tanks are lightweight and corrosion-resistant, while robust fittings (petcock valves, brass components) improve longevity in rugged riding conditions.
- Mounting and handling: Look for secure connections and easy mounting options that do not interfere with riding controls or other motorcycle components.
- Maintenance potential: Some models are geared toward servicing and carb balancing, while others emphasize onboard fueling for extended trips. Determine which use-case aligns with your needs.
- Budget and availability: Consider the value offered by kit inclusions (hose, valve, lid) and whether the model covers your most common motorcycle types and maintenance workflows.
These products collectively address extended-range riding, maintenance and tuning tasks, and general fuel-availability challenges encountered by riders across a range of motorcycle setups. When selecting an auxiliary tank, prioritize compatibility, control, and durability to ensure safe, reliable operation in the field.
