GasTapper R-Max

$139.95 $179.95

The GasTapper R-Max has a larger case and moves double the volume of the GasTapper Standard. The R-Max transfers up to 60 gallons per hour. This unit can dry lift up to 20 feet high and overall lift to 30 feet. The included fume-proof case measures 12"x 14"x 5" and weighs eight pounds. The case provides lots of room for easy stowing and extra supplies. This unit has 16 feet of fuel line, an additional six feet of 5/16 inch semi-rigid vehicle access line, a fuel filter, spare filter, two Hose-Man® hose clips, brass pickup weight, and a capless access funnel. This model does not include a remote. 

The GasTapper R-Max is not compatible with any amount of water. A single drop will seize the pump. If you are looking for a pump that is compatible with fuel and water, please check out our Gas Guzzler.

Flow rate is under optimal conditions and is purposely low for safety purposes. This product comes with a one-year warranty. The 12V GasTapper R-Max is assembled in the USA with US and imported components. The case, power cord, and hose clips are made here in the USA! The pump is imported from Asia and is a high-quality German design. 

If vehicle access is desired, please order our car access kit to test your vehicle first.

Great systems

Have both the Aqua and Gas Tapper R-Max. Both work well and are built well. Service was outstanding when ordering.

Great pump and company

Use the R-Max to drain the unused gas out of boat tank every couple of years to prevent issues with the engine. Had problem with the pump not working right this year, and Daniella from the company walked me through troubleshooting it and sent me out a new wiring harness right away. It is up and running again and it works as advertised. Highly recommended.

Works great

I use the GasTapper R-Max to refuel my Bristell airplane. More practical than other methods I’ve used.
