oil pump for Minarelli 50cc

Aftermarket oil pump in original design and flow. A defective oil filter can cause seizing, or damage the crank and bearings. Such a small part makes a huge difference. Only suitable for horizontal Minarelli engines. Please note that when changing the oil pump, you should do one fuel tank fill up at a ratio of 1:50. This helps to air the pump and the lines after installation, without damaging the engines.
