Baudelio Fuel Transfer Pump 3.8 GPM with Auto-Stop — 51" Hose, 12V DC/AA Portable No-Spill Gas & Diesel Pump with 4 Adapters

This compact transfer pump is built to speed up fuel and oil moves while reducing spills and waste. Designed with a long 51-inch discharge hose, four universal adapters and dual power modes (AA battery or 12V DC), it fits into work trucks, workshops and boats for quick, dependable fluid transfer. The no-spill auto-stop sensor helps you avoid overflow, and the pump’s improved flow design delivers faster extraction compared with basic siphons.

How quickly will it transfer fuel?

The Baudelio pump offers a maximum flow rate of up to 3.8 gallons per minute thanks to its improved flow design, which increases extraction efficiency. Using the 12V DC power source typically gives the most consistent high flow, while AA battery power is useful for short, emergency jobs.

• Top performance: up to 3.8 gallons per minute for fast transfers.
• 12V DC mode: delivers the most stable and powerful flow.
• AA battery mode: portable backup for remote or emergency use.

Will it prevent spills and overfilling?

Yes — the unit includes an automatic stop sensor that detects when the receiving tank is full and stops pumping to reduce overflow and fuel waste. The pump’s leak-protection features and precise auto-stop help keep transfers clean and controlled, particularly when working with tight vehicle fuel openings or small containers.

• Auto-stop sensor: halts flow at full tank to avoid spills.
• Leak protection: design minimizes drips during and after transfer.
• Nozzle cover and storage bag: keep the pump and hose clean between uses.

Which fuel containers and engines does it fit?

The pump ships with four universal adapters sized to match most gas cans and tanks, covering a wide range of openings from small lawn-mower cans to larger jerry cans and vehicle filler points. The flexible 51-inch hose reaches into deep containers and trunks so you can extract nearly all the liquid without tilting heavy containers.

• Adapters included: 2", 2.1", 2.75" and 3.75" for broad compatibility.
• 51-inch hose: long, flexible reach into trunks or deep fuel cans.
• Suitable for gasoline, diesel, and oil on cars, boats, mowers and more.

How is the pump powered and maintained?

The Baudelio transfer pump supports two power options: plug into a 12V DC supply for best performance or insert four AA batteries for a portable alternative. Routine care is simple — flush the hose after use, store the unit in the included bag, and protect the nozzle with its cover to extend service life.

• Dual power: DC 12V cable for strongest flow; 4x AA battery backup for portability.
• Easy upkeep: flush hose and cap nozzle after each use to prevent residue buildup.
• Durable design: made for frequent use in garages, boats, and job sites.

Who is this for? The Baudelio Fuel Transfer Pump is aimed at vehicle owners, small-fleet operators, marine enthusiasts, landscapers and DIY mechanics who need a fast, portable way to move gasoline, diesel or oil without frequent spills. It’s also useful as an emergency siphon in roadside or remote situations where access to a 12V supply may be limited and AA batteries offer a reliable backup.
