The Rhino-Pak and Desert Patrol are built to take a beating and hold five and a half or six gallons without complaint. Getting the water back out is another story. The hose they come with is gravity fed, so it glugs, it splashes, and it stops and starts as air works its way back in. The Lone Rock Concepts Rhino-Pak Overland Water Pump Adapter Kit turns your container into a hands-free faucet with a steady stream instead. Press the button and water flows at the same rate from the first pour to the last. Wash dishes, fill a cup, rinse hands, clean gear. No tipping a full jug. No spills. Go Beyond Gravity.
Yes. If you have a Reliance Rhino-Pak or Desert Patrol in any size, this kit fits.
Important: Does not fit Reliance Aqua-Tainers. If you have an Aqua-Tainer or Jumbo-Tainer, we have a dedicated Reliance Aqua-Tainer kit available separately.
