## Discrepancy

SAID HOSE IS MADE FROM TEFLON.  IF INSTALLED INCORRECT OR CARELESSLY, CAN TEND TO TWIST.  AFTER A RECENT TURBOCHARGER INSTALL, ALL THREE OF NOTED HOSES WERE TWISTED.  THIS CAN RESULT IN RESTRICTED OR BLOCKED OIL FLOW.  WHEN INSTALLING THESE HOSES USE THREE WRENCHES; ONE ON HOSE BODY FITTING, ONE TO TIGHTEN HOSE B-NUT, AND ONE TO SUPPORT TURBO DRAIN TANK FITTING.
