The ATF flows thru this tube from the motor to the lift cylinders. What's ATF? Shame on you! Auto-Matic-Trans-Mission-Fluid, Right? Each Convertible takes 2 fluid tubes. Two tubes per car. One is fitted to the bottom of the rams & motor and the other tube is fitted to the top of the rams & motor. One for up and one for down. This item is for 1 each.
