porotmotor 1L Motorcycle Auxiliary Fuel Tank — Translucent Gravity‑Feed Service Tank with Shut‑Off Valve

Porotmotor's 1L motorcycle auxiliary fuel tank is a portable, gravity-fed service tank designed to supply temporary fuel for carburetor tuning, synchronization and maintenance when the main tank is removed.

When you're adjusting carburetors or working on fuel systems, repeatedly reinstalling the bike's main tank is awkward and time-consuming. This translucent 1‑liter service tank gives you a stable, visible fuel source that hangs above the engine for reliable gravity feed. Built-in scale marks, a vented cap and an inline shut-off valve streamline testing while keeping the setup compact and workshop-friendly.

How does this tank make carburetor tuning easier?

Removing the motorcycle's main tank exposes the carburetors but cuts off fuel. The Porotmotor auxiliary tank restores a steady feed without full reassembly, so you can tune jets, idle and synchronization in place. Its vented cap prevents vapor lock and the shut-off valve lets you stop flow instantly for adjustments.

• Gravity-fed design maintains a constant, simple fuel supply
• Translucent body with scale marks shows remaining liters
• Inline shut-off valve for quick start/stop during adjustments
• Integrated hook suspends the tank above the engine for consistent pressure

What safety and usage features should I know about?

This tank is built specifically for temporary service use, not long-term fuel storage. Secure hose connections, position the tank away from hot components and drain leftover fuel into an approved container after testing. The vented cap promotes steady flow but always follow workshop safety practices.

• Vented cap reduces pressure fluctuations during feed
• Shut-off valve prevents unintended fuel flow while working
• Material is translucent for easy visual fuel checks
• Not intended for permanent installation or long-term storage

Which motorcycles and tasks is this compatible with?

The Porotmotor 1L auxiliary tank suits most carbureted motorcycles, scooters and small engines that accept a gravity-fed supply. It’s ideal for single or multi-carb setups when the factory tank is removed, and for bench testing small engines where a compact, visible fuel source helps diagnose running issues.

• Works with most carburetor-equipped bikes and small engines
• 1L volume supports extended tuning sessions without refilling
• Hooked design adapts to frames or workshop stands for mounting
• Translucent scale helps measure fuel consumption during tests

How do I install and maintain the service tank safely?

Hang the tank so it sits above the carburetor inlet, connect the fuel line securely, then open the shut-off valve to start flow. After testing, close the valve and drain remaining fuel into an approved container; store the tank empty and clean. Regularly inspect hoses and fittings for wear before each use.

• Mount hook high enough to ensure gravity feed pressure
• Use correct fuel hose diameter and clamp connections
• Close valve before disconnecting to avoid spills
• Drain and ventilate the tank between uses to avoid fuel degradation

Who this is for: Technicians, DIY motorcycle mechanics and hobbyists who perform carburetor adjustments, synchronization or engine bench testing will find the Porotmotor 1L auxiliary fuel tank a practical shop tool. It simplifies temporary fueling when the main tank is removed, gives clear visual fuel monitoring, and helps speed routine adjustments without modifying the bike. Note: this product is intended for temporary service use only; follow all fuel-handling and workshop safety guidelines.
