Oil Extractor Pump - A very clever Vacuum pump with a multitude of uses both on board and at home. Between 10 to 20 strokes of the pump creates a powerful vacuum, which can then suck out your dirty engine oil or any other inaccessable area such as bilges. The dirty oil is captured inside the container which holds 6 litres and has calibrated sides, so you know how much you've taken out. The pump screws off for easy storage onboard.
