The Magic Pump is a pump for transferring fuel, water, etc, without electricity. The pump works on the siphon principle, therefore the supply tank must be higher than the receiving tank. Just agitate the pump head vigorously in the supply tank until the tubing fills, then, the liquid will then continue to flow until the pump head is lifted from the liquid or the supply tank is empty.
Ideal for refuelling at sea, or buying less expensive fuel at supermarket rather than Marina.
Also good for, say, emptying the bath for watering the garden, or from a water butt, plus many other uses in a caravan, aquarium, car…
