This little wonder is incredibly versatile and can handle air, gas, coolant, fuel, oil, water, and more. From refueling your vehicle to draining sinks or transferring gas, this pump has got you covered. We first discovered the need for this (along with absorbent sponges) when we had one of the seals around a compartment fail and there was no other way to get the sitting water out. It’s an emergency tool to keep in your RV toolkit, and it’s super portable and practical. Just connect the PVC hoses, give the rubber bulb a few squeezes, and watch the fluid flow automatically. Plus, the durable rubber ball has a one-way valve to prevent any messy backflow. Don’t hit the road without this essential and reliable manual siphon pump!
