The problem
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH BI-FUEL COMPRESSED NATURAL GAS (CNG) VEHICLES. THE CNG FUEL LINE AND THE CNG HIGH PRESSURE REGULATOR COOLANT LINES CAN CONTACT OTHER FUEL (GASOLINE) AND BRAKE LINES ON THE VEHICLE. ABRASION FROM CONTACT CAN CAUSE A LEAK IN THE BRAKE PIPE, FUEL PIPE, OR BOTH.
Risk
ABRASION FROM CONTACT CAN CAUSE A LEAK IN THE BRAKE PIPE, FUEL PIPE, OR BOTH. A BRAKE FLUID LEAK COULD DISABLE A PORTION OF THE BRAKE SYSTEM, CAUSING LONGER STOPPING DISTANCES. GASOLINE LEAKING FROM A FUEL PIPE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD CAUSE A VEHICLE FIRE.
What owners should do
DEALERS WILL INSPECT AND REPOSITION THE CNG FUEL AND COOLANT PIPES AND REPOSITION/REPAIR ANY DAMAGED FUEL OR BRAKE PIPES AS NECESSARY.
