617 Turbo Diesel ALDA Pressure Line

Fits the following 116, 123, and 126 chassis to 1985. This is a very important line on the 617 turbo diesel engines that often breaks or becomes plugged. When it does you will lose power. It will feel like you are dragging an anchor or give you the indication your turbo is not working. This line runs from the back of the intake manifold to a switch on the firewall and then to the ALDA (altitude compensator) on top of your injection pump.
