Hand Fuel Siphon Pump Silver 12 mm Valve, Manual Bulb Suction Pump for Fuel

The Silver Hand Fuel Siphon Pump features a manual bulb suction design with a 12 mm valve for controlled transfer of petrol, diesel and other compatible liquids. This compact, hand-operated pump does not require electricity and is intended for occasional decanting, maintenance tasks and emergency refuelling where a simple, portable solution is preferred. The construction and valve diameter are designed to fit many common filler openings and small fuel lines, enabling direct suction from tanks, drums or portable containers.

Advantages

The bulb suction mechanism offers tactile control over flow rate and helps prevent spills during transfer. Its manual operation eliminates the need for power, making the pump usable in remote locations or during power outages. The 12 mm valve provides compatibility with a range of fuel openings and hoses, and the compact form factor allows easy storage in toolboxes or vehicle compartments.

Suitable for

• Transferring petrol and diesel between tanks, drums and portable containers
• Decanting small quantities of fuel for maintenance of lawnmowers, generators, motorcycles and boats
• Emergency refuelling and on-site fluid transfer where no electric pump is available

Key specifications

• Operation: manual bulb suction (hand-operated)
• Valve/connection diameter: 12 mm
• Compatible fluids: petrol, diesel and similar low-viscosity liquids (check chemical compatibility before use)
• Material: durable lightweight plastics and rubber components for the bulb and hoses
• Portability: compact, handheld design for easy storage and transport

How to use

Insert the suction hose into the source container and position the discharge end into the receiving container. Squeeze the bulb repeatedly to create suction until fluid begins to flow, then maintain a steady squeeze-and-release rhythm to transfer the required quantity. After use, close the valve if present, drain residual liquid, and rinse the hoses and bulb with an appropriate cleaning fluid if switching between different fuel types. Store the pump in a clean, dry place away from direct sunlight and sources of heat.

Usage recommendations

Use only with fuels and liquids that are compatible with plastic and rubber materials. Avoid using with hot liquids or highly corrosive chemicals. Work in a well-ventilated area, keep sparks and open flames away from the work area, and wear appropriate gloves and eye protection when handling fuels. Regularly inspect hoses and the bulb for cracks or wear and replace components as needed to maintain safe operation.
