GasTapper Fuel Transfer Pump — Hand Siphon Pump 3.5 GPM with 9 ft Hose & Brass Tip

GasTapper Gas Siphon Pro Pump is a compact hand-operated transfer pump that moves gasoline, diesel, oil, water and other liquids up to 3.5 gallons per minute with a 9-foot hose and brass-weighted nozzle.

When you need to move fuel or other liquids quickly without electricity, this manual siphon pump is built for reliability and portability. It’s designed for vehicles, small equipment, boats, gardens and emergency tasks where an easy-to-control flow and a long hose make a real difference. The kit includes a durable pinch clip to stop flow, a brass tip weight to sink the hose, and straightforward assembly for fast use.

How fast and how much liquid can it move?

The GasTapper pump delivers up to 3.5 gallons per minute under normal siphoning conditions, making short work of small tanks and containers. Flow rate will vary with elevation, liquid viscosity and user pumping rhythm.

• Maximum flow: 3.5 gallons per minute (typical for gasoline/water)
• Effective for oils and diesel with slightly reduced speed
• Manual operation — no batteries or power source required
• Consistent flow control via the included pinch clip clamp

Can I use it for different fluids and situations?

The GasTapper is multi-purpose, suitable for gasoline, diesel, motor oil, water and similar fluids. It’s useful for refilling small engines, draining water from basements, transferring liquids between containers, or removing water from an aquarium or bilge.

• Safe for petrol, diesel and common motor oils (avoid solvents not recommended for rubber hoses)
• 9-foot hose reaches deep tanks, wells, and hard-to-access containers
• Brass nozzle acts as a weight for submerged placement and stability
• Portable for roadside, garage, workshop, boat, or garden use

How do I start, stop and control the flow?

Starting is simple: insert the weighted brass nozzle into the source, prime the pump by hand action and let gravity assist the siphon. Stopping or regulating flow is handled quickly with the pinch clip clamp attached to the hose, so you can pause transfers without repositioning the pump.

• Hand-operated priming — no priming pumps or electrical hookups needed
• Pinch clip clamp for instant stop or flow throttling
• Brass tip helps maintain submerged position while pumping
• Quick assembly in minutes for emergency or routine transfers

What maintenance or care does the pump need?

Rinse and drain the hose after use when switching fluids or storing for long periods. Inspect the hose and fittings for cracks or hardening and replace if damaged to maintain safe transfers.

• Flush with appropriate cleaning fluid (water for water, light oil for fuel residues)
• Dry fully before storing to prevent contamination or mold
• Store away from direct sunlight and extreme heat to preserve hose life
• Check brass nozzle and clamp for secure fit before each use

Who is this for? The GasTapper Gas Siphon Pro is ideal for homeowners, boaters, motorcycle and lawn equipment owners, and anyone who needs a reliable, portable way to transfer small-to-midsize volumes of liquid without power. It’s particularly useful for emergency drains, quick refills, garage maintenance and outdoor work where compact, easy-to-control equipment matters.
