FUEL/PROPULSION SYSTEM
I FIRST NOTICED THAT THE ANTI-LOCK BRAKES WERE ACTIVATING AT SLOW SPEEDS ( 5-10 MPH ) UNDER DRY ROAD CONDITIONS. THIS WAS PRIOR TO BRAKE LINE INCIDENT ON 4-14-2012 BUT I AM NOT SURE OF EXACT DATE. I RESEARCHED THE ANTI-LOCK BRAKES AND FOUND NHTSA ID CAMPAIGN #05V379000 ACTION # PE05020 BUT THIS DID NOT INCLUDE MY HOME STATE OF KENTUCKY. HOWEVER, I HAVE BEEN WORKING IN OHIO SINCE THE PURCHASE OF SAID VEHICLE 10-17-2001 TO CURRENT DATE 2-11-2013. ON 4-14-2012 I WAS PREPARING TO TAKE MY BOAT TO FUEL IT . WHILE CHECKING THE TRAILER LIGHTS I STEPPED ON THE BRAKE PEDAL AND IT WENT STRAIGHT TO THE FLOOR. I FOUND THAT THE BRAKE LINE TO THE REAR WHEELS HAD BURST IN HALF AND WAS SEVERELY CORRODED. UPON CLOSER INSPECTION I FOUND THAT ALL THE BRAKE LINES SHOWED SIGNS OF SEVERE CORROISION. ON 2-8-2013 I DISCOVERED THAT DIESEL FUEL WAS LEAKING NEAR THE FUEL TANK AND FUEL COOLER. IT WAS FOUND TO BE A CORRODED RETURN FUEL LINE BETWEEN THE COOLER AND THE FUEL TANK .AGAIN UPON CLOSER INSPECTION ALL FUEL LINES SHOW MODERATE TO SEVERE CORROISION. *TR
