The main pump draws fluid from a tank positioned in the right wing behind the main spar at WS 127. In order to install the tank two holes are cut in the wing skin. One hole will allow the insertion of the bladder style fluid receptacle and the other hole is cut for the filler port.




Padding is installed to line the cavity prior to tank installation and doublers are installed to strengthen the structure supporting the filler port and access hatch.



Both wing tips are removed and the aileron unhinged. A tank vent is installed in the right wing tip rib and a 3/16″ nylon tube is run from the tank to the vent.

The tank installation is finished with the installation of the access hatch and filler port. A locking cap is installed in the filler port to lower the opportunity for foreign fluids or debris to enter the TKS system.

When the fluid is drawn from the tank it passes through a strainer into nylon tubing designed for TKS fluid and the pressure requirements of the TKS system. The fluid is pulled through the main pump and then pushed through the filter to the proportioning units in each wing and the tail.
