I purchased this item to pump out a boats fuel tanks that was being laid up for repairs.I was a little skeptical at first having read the previour reviews of non-priming and hose joints failing etc, but decided to take a risk.The pump arrived promptly in good order and I was pleased to see that the pressure hose was of the crimped fitting variety with O ring joints.We set the pump up on the jetty side with the suction hose going straight into the tank, and the outflow being discharged approximately 30 meters away by a connected lay flat hose.The pump was powered by a 5kVa generator which coped easily/On starting the pump it primed straightaway with no additional help and discharged nearly 1000 litres in just under half an hour, quite acceptable given the lift and distance.Overall very pleased with the purchase and would recommend this product as received.
