VierKate Portable Fuel Transfer Pump — 3.8 GPM, 80" Intake Hose, Auto-Stop & Hand Nozzle (USB-C/12V/AA)

The VierKate Portable Fuel Transfer Pump is a compact, all-in-one transfer system with an auto-stop sensor and hand nozzle that moves fuel quickly and safely between containers without adapters.

This lightweight pump is designed for homeowners, mechanics, boaters and farmers who need a clean, controllable way to move gasoline, diesel, kerosene, DEF or non-potable water. Its 80" intake hose, slidable clamp and three power options (USB-C, 12V battery clips or four AA batteries) let you reach tanks and barrels of different depths while avoiding messy spills and ill-fitting adapters.

How does the auto-stop and hand nozzle improve refueling tasks?

The pump combines a sensitive auto-stop sensor with a sturdy hand nozzle so you can choose automatic shutoff for fill-to-full or manual control for partial transfers. The auto-stop catches the rise in liquid and shuts off flow, while the nozzle lets you pause or resume without changing fittings.

• Sensitive sensor prevents overfill and reduces spills.
• Sturdy hand nozzle for precise manual transfers.
• Integrated rubber ring in the hose reduces leaks and keeps the seal tight.

Will this fit different gas cans and barrel depths without adapters?

Yes — the pump uses a slidable clamp module and a long 80" intake hose so one unit adapts to mini cans and tall barrels alike. You won’t need a drawer full of adapters; just slide the clamp to secure the hose in the opening and adjust depth as required.

• Slidable clamp fits necks larger than 1.25" without additional parts.
• Long hose reaches deep tanks and high barrels for flexible use.
• Rubber-covered clamp eliminates gaps that could let dirt or debris enter the fuel.

What power options are available and where can I use this pump?

The VierKate pump supports three common power sources: USB-C for portable battery packs, DC 12V clips for vehicle batteries, or four AA batteries for cordless operation. This multi-power design lets you operate the pump at job sites, in a garage, at the marina, or on the road without searching for a single dedicated power supply.

• USB Type-C input for power banks and modern chargers.
• 12V battery clips for direct vehicle battery connection on larger jobs.
• 4x AA battery option for quick, cable-free transfers in the field.

How fast and how much can it pump safely?

The unit moves fuel at up to 3.8 gallons per minute, offering a balance of speed and control for routine transfer tasks. The integrated auto-stop and tight hose seal help maintain safety and reduce waste while you transfer larger volumes efficiently.

• Maximum flow rate: approximately 3.8 GPM for quick fills.
• Auto-stop prevents overfilling and reduces cleanup time.
• Designed for gasoline, diesel, kerosene, DEF and non-potable water.

Who this is for: The VierKate Portable Fuel Transfer Pump is ideal for anyone who regularly moves liquids between containers — home mechanics topping off lawn equipment, boat owners filling outboard tanks, farmers transferring diesel, or roadside responders topping up equipment. It’s especially useful when you need one reliable pump that fits various container sizes, works from multiple power sources, and minimizes spills and adapters.
