## Discrepancy

THIS HOSE IS MADE FROM TEFLON.  IF INSTALLED INCORRECTLY OR CARELESSLY, THESE HOSES TEND TO TWIST.  HOSES ON SAID AIRCRAFT APPEAR TWISTED WHICH CAN RESULT IN RESTRICTED OR BLOCKED OIL FLOW.  AFTER OPERATING AIRCRAFT WITH HOSES TWISTED, THEY TEND TO HOLD THEIR TWISTED SHAPE.  WHEN INSTALLING THESE HOSES, THREE WRENCHES MUST BE USED, ONE ON THE HOSE BODY, ONE TO TIGHTEN HOSE B-NUT, AND ONE TO SUPPORT FITTING ON TURBO DRAIN TANK.
