WINTOWIN Auxiliary Motorcycle Fuel Tank 1L – Portable Reserve with Brass Petcock & 108cm Hose

If you ride long distances, test carburetor setups, or need a dependable emergency reserve, this lightweight 1,000 ml auxiliary tank was made for quick refueling and diagnostic work. Molded from ABS with a clear volume scale, a large filler cap with air outlet, and a solid brass petcock, the kit includes an 108 cm fuel hose, cut-off valve, mounting chain, and hook so you can outfit nearly any motorcycle, mower, or small-engine vehicle.

How does this auxiliary tank help when synchronizing carburetors?

It provides a steady, gravity-fed fuel source that removes variables caused by the motorcycle's main tank or pump during tuning. With a reliable external supply you can test jets and balances without fuel starvation or intermittent flow changes, improving the accuracy of adjustments.

• Steady gravity feed reduces fuel supply fluctuations during tuning
• Clear capacity scale lets you monitor consumption while adjusting
• Brass petcock and cut-off valve allow precise on/off control
• 108 cm hose reaches carburetors on most motorcycle layouts

Will this work on different motorcycles and small engines?

The tank is designed as a universal auxiliary reservoir suitable for many carbureted bikes and fuel-injected systems with external pumps, plus small equipment like mowers. Its simple hose-and-petcock hookup fits standard fuel line sizes, making it compatible with a wide range of models without complex adapters.

• Universal 1L capacity for scooters, dirt bikes, cruisers, and commuters
• Compatible with external pump fuel-injection systems and carburetors
• Can also feed small engines such as mowers and generators
• Includes mounting chain and hook for secure attachment

How durable and easy to use is the WINTOWIN auxiliary tank?

Constructed from ABS plastic, the tank is lightweight yet resilient to road vibration and handling. The large filler cap with an air outlet streamlines refilling, while the visible fuel scale and brass petcock make operation straightforward for riders and mechanics.

• ABS construction resists impact and weather for field use
• Clear scale for quick visual fuel checks on the go
• Generous filler cap simplifies topping up without spills
• Solid brass valve provides reliable, corrosion-resistant control

How should I mount and maintain this auxiliary tank?

Mount it using the included chain and hook in a secure spot that keeps the hose clear of hot parts and the wheel. Rinse and drain the tank after use, inspect the hose and petcock for wear, and store dry to prevent contamination and prolong life.

• Mount with chain and hook away from exhaust and pinch points
• Route hose to avoid sharp bends or heat sources
• Drain and clean after fuel tests to prevent residue build-up
• Replace aged hose or valve if leaks or cracks appear

Who is this for? Riders, mechanics, and DIY tuners who need a portable, dependable fuel reserve or a stable test supply will appreciate the WINTOWIN auxiliary tank. It’s especially useful for long-distance adventurers, commuters seeking a backup, garage technicians tuning carburetors, and owners of small engines who want a lightweight, universal fuel solution.
