porotmotor Auxiliary Fuel Tank 1L Ventilated — Portable Carburetor Tuning with Calibrated Valve

porotmotor's 1L ventilated auxiliary fuel tank is a compact temporary fuel supply made to feed a carburetor for tuning and small-engine diagnostics safely and precisely.

This lightweight, workshop-ready tool gives mechanics and hobbyists a controlled, visible fuel source when adjusting jetting, idle mixtures, or diagnosing engine behavior without relying on the vehicle’s main tank. Built from chemical-resistant polymer with stainless fittings and a vented cap, the unit balances durability with portability. The calibrated valve and flow markers let you change flow rate while observing engine response, making short-term tuning sessions faster and cleaner.

How does this tank simplify carburetor tuning?

By delivering a steady, isolated fuel feed directly to the carburetor, the porotmotor auxiliary tank removes variables tied to the bike’s fuel system—such as clogged lines or faulty petcocks—so you can focus on jet size and mixture adjustments. The visible flow markers and calibrated valve make incremental adjustments repeatable across testing runs.

• Direct feed to carburetor avoids main-tank interference
• Calibrated valve allows precise flow changes during runs
• Visible markings provide immediate feedback on fuel delivery
• Vented cap stabilizes pressure for consistent output

Is it safe for workshop use and short-term testing?

The device is intended for temporary fuel supply only and is constructed from chemical-resistant polymers and stainless-steel fittings to tolerate typical fuel handling in a repair environment. Follow the included safety guidance: seal clamps and hoses, use only as directed, and drain residual fuel after each session to reduce risk.

• 1L capacity optimized for short diagnostic sessions, not storage
• Stainless fittings resist corrosion from fuels and additives
• Vented cap reduces vapor lock and pressure spikes
• Hanging hook keeps the tank secure and out of the work area

How do I mount and operate the auxiliary tank during a tuning session?

Mount the tank using the integrated hook on handlebars, a shelf, or workshop fixture at a slightly elevated position to allow gravity feed. Connect the fuel line to the carburetor, confirm clamps are tight, open the calibrated valve incrementally, and observe engine response while adjusting jetting or mixture screws.

• Hang from handlebars or workshop fixture with built-in hook
• Connect fuel hose to carburetor inlet; tighten clamps securely
• Use valve to start with low flow, increase gradually as needed
• Drain and clean after each use to prevent residue buildup

What maintenance and precautions should I follow?

Rinse and dry the tank after each session and inspect hoses and fittings for wear before reuse. Use only for temporary diagnostic feeds—do not leave fuel stored in the tank long-term—and follow local regulations for fuel disposal. If you encounter any fitting leaks or valve issues, stop use and contact support.

• Empty and ventilate after every session to avoid stale fuel
• Check clamps, hoses, and valve seals frequently for integrity
• Store dry and away from heat or ignition sources between uses
• Contact porotmotor support for troubleshooting or replacements

Who is this for: The porotmotor 1L ventilated auxiliary fuel tank is designed for motorcycle mechanics, small-engine technicians, and hands-on enthusiasts who tune carburetors or diagnose fuel-related running issues. It’s ideal for short-term testing, bench setups, and trackside adjustments where precise, visible fuel flow and a compact, durable tool are required.
