RC Car Fuel System

This is not for real petrol but for water. you get a Lego Technic pneumatic pipe an put it in the small hole and the exhaust on the other when a belt is connected to the pulley the pump will spray water droplets out the exhaust so it looks realistic
i will be printing this soon
there is a small fuel tank which you can use if you do not have one which will fit the Lego pipe fine.
