We met Keith Lellis at the wonderful Halifax Caravan Park at Nelsons Bay. It was a typical CMCA scenario - we were leaving in a hurry, then met Keith and three hours later we got on the road! Judy Lellis told us that Keith was very careful with money and was forever running out of diesel! Being of "mature" years he also has a bad back and carrying the Jerry cans from the rear to fill up was not a good move. He discovered this novel way of transferring fuel. All you do is insert the gadget into a Jerry can, run a hose to your fuel tank and attach any el-cheapo tiny air compressor. This makes the fuel flow. The device does have a safety pressure release valve however the unit is not designed to be used with larger compressors as it could be dangerous. Keith gave us a demo and it worked really well. There is a website somewhere, but for the life of us we can't find it - can anyone help please?
