MADHOLLY Hand Fuel Transfer Pump Kit — 3/4" Brass Connector, Leakproof Stainless Clamps, Portable Manual Pump

MADHOLLY Hand Fuel Transfer Pump with Leakproof Clamps is a compact, manual pump kit that safely moves gasoline, diesel, oil, antifreeze, kerosene, and water with secure stainless-steel clamps and a 3/4" brass connector.

This portable pump kit is designed for everyday maintenance and emergency refueling tasks where electricity or powered gear isn’t available. The set includes the pump body, two flexible PVC hoses, three heavy-duty stainless-steel leakproof clamps, and a 3/4" NPT brass connector so you can hook into standard fittings. Built to resist kinking and chemical degradation, the components are suitable for garage jobs, campsite use, RV winterizing, and small-engine service.

How does the pump keep fuel lines leak-free?

The MADHOLLY kit uses three heavy-duty stainless-steel clamps to create tight seals at hose joints and the brass connector. That combination minimizes drips and prevents hazardous spills when transferring flammable liquids or oil. The clamps are corrosion resistant and sized to match the included hoses and fittings, giving a reliable, repeatable connection.

• Three stainless-steel leakproof clamps included
• Clamps sized for the pump hoses and brass connector
• Reduces drips and improves safe handling of fuels

What liquids can I use this pump with?

This hand pump is formulated to handle a wide range of non-corrosive automotive and household liquids, including gasoline, diesel, kerosene, motor oil, antifreeze, and plain water. The pump body and PVC hoses resist the common solvents found in these fluids, so you can rely on the kit for vehicle maintenance, lawn equipment service, and antifreeze filling for RVs. Avoid use with unknown corrosive chemicals or concentrated acids.

• Compatible: gasoline, diesel, kerosene, motor oil, antifreeze, water
• Not recommended for strong acids, bases, or reactive solvents
• PVC hoses resist kinks and cracking for long-term use

How easy is the pump to carry and set up?

The pump is lightweight and ready to use straight from the box—no tools required for basic assembly. Hoses slip onto fittings and lock in place with the included clamps; the 3/4" brass connector fastens to common RV and municipal fittings for antifreeze or water fill tasks. Its compact footprint fits in a trunk, tool bag, or campsite box for quick access when you need it.

• Kit includes pump, two hoses, three clamps, and 3/4" brass connector
• Tool-free hose attachment for fast setup
• Compact, portable design for travel and roadside use

Will the kit work with RV city water or antifreeze lines?

Yes—the included 3/4" NPT brass connector adapts the pump to standard RV city water inlets and many common antifreeze filling points. The brass fitting provides a secure, corrosion-resistant connection and pairs with the leakproof clamps to reduce fluid loss during filling. This makes winterizing an RV or topping off tanks simpler without powered pumps.

• 3/4" brass connector for RV city water and antifreeze openings
• Secure sealing with clamps prevents spills during filling
• Brass resists corrosion for durable field use

Who this is for: The MADHOLLY Hand Fuel Transfer Pump is ideal for vehicle owners, RV and camper operators, landscapers, small-engine mechanics, and outdoor enthusiasts who need a dependable manual fluid-transfer tool. If you want a portable, non-electric solution that minimizes leaks and adapts to standard fittings for fuel, oil, antifreeze, or water, this kit provides an affordable, durable option for home garage, roadside, or campsite tasks.
