1986 Winnebago Winnebago

ANALYSIS OF THE MANUFACTURER INFORMATION:IT APPEARS THAT THE PROBLEM OCCURS ON THE WINNEBAGO MOTORHOMES EQUIPPED WITH AN AUXILIARY FUEL TANK AND HIGH UNDERCARRIAGE TEMPERATURES.ANALYSIS:FUEL RESERVOIR OVERPRESSURE RESULTS WHEN THE MOTORHOMES EQUIPPED WITH AUXILIARY FUEL TANKS ARE EXPOSED TO HIGH UNDERCARRIAGE TEMPERATURES WITHOUT A MODIFIED FUEL CAP AND EVAPORATIVE EMISSION CARBON CANISTER.THE EXISTING COMPONENTS MAY NOT REDUCE THE FUEL PRESSURIZATION THAT CAN RAPIDLY BUILDUP FROM THE LARGE SURFACE AREA OF THE PRIMARY FUEL TANK.OPERATING THE VEHICLE FROM THE AUXILIARY FUEL TANK WITH THE PRIMARY TANK FULL COMPOUNDS THE PROBLEM.HIGH UNDERCARRIAGE TEMPERATURES INCREASE THE FUEL VAPORIZATION.STATUS:WINNEBAGO HAS RECALLED THE SUSPECT VEHICLES TO ALLOW VENTING THEOVER PRESSURE (87V-155).CLOSED 1/6/88. #===

WHEN I PURCHASED MY USED MOTOR HOME 4 YEARS AGO, I REPLACED ALL THE TIRES BECAUSE THEY WERE ALL 10 YEARS OLD AND CRACKING, I INSTALLED 6 DELTA LT215/85R16 110/107S AIERRADIAL A/S , THAT WAS APPARENTLY A MISTAKE BECAUSE SINCE THEN 3 TIRES HAVE FAILED WITHOUT PUNCTURE WITH MASSIVE TREAD SEPARATION AND RAPID DELFATION(ONE FRONT AND 2 REAR). I MAINTAIN MY TIRE PRESSURE AT 65PSI COLD VERY CAREFULLY AND THESE TIRES SHOWED NO LOSS OF PRESSURE BEFORE THE FAILURES. NO SIGNIFICANT LOSS OF CONTROL OCCURRED, BUT HUBCAPS AND TIRES WERE DESTROYED. THEY WERE REPLACED WITH SIMILAR DIFFERENT BRAND TIRES. *TR

ABOUT 8 MILES AFTER SWITCHING FROM MAIN FUEL TANK TO AUXILIARY TANK, WITH THE DASHBOARD SWITCH, STARTED SMELLING FRESH GASOLINE. IT BECAME WORSE AND WORSE, FOR THE NEXT SHORT DISTANCE,. I EXITED THE HIGHWAY, AS QUICKLY AS I SAFELY COULD, AND CHECKED OUT THE CAUSE OF THE GASOLINE SMELL BEING SO SEVERE, AND FOUND THE GASOLINE JUST FLOWING, CONSTANTLY, OUT THE BOTTOM OF THE CHARCOAL CANISTER, A STREAM THE DIAMETER OF A PENCIL. THE FLOW OF GASOLINE FROM THIS SITE DID NOT DIMINISH BY ANY AMOUNT, UNTIL I SWITCHED THE DASH SWITCH BACK TO THE MAIN FUEL TANK, AND ALSO REMOVED THE CAP FROM THE SMALL FUEL TANK. THE FLOW OF GASOLINE SLOWED, A SMALL AMOUNT, BY DOING THIS, AND I DROVE THE VEHICLE BACK HOME AND PARKED IT. BY THE TIME I GOT IT PARKED, THE FLOW OF GASOLINE FROM THIS SITE HAD STOPPED, COMPLETELY. FUEL WAS ALSO LEAKING FROM THE AUXILIARY TANK, ALL ABOUT THE PASSENGER SIDE, AT THE BOTTOM OF THE TANK, BUT NOT AS BADLY AS THE FLOW FROM THE CHARCOAL CANISTER. THIS SURELY POSES A VERY DANGEROUS THREAT TO HUMAN LIFE; NOT ONLY MY OWN, BUT ANYONE WHO MAY HAVE BEEN AROUND, HAD AN EXPLOSION TAKEN PLACE, WHICH COULD VERY EASILY HAVE HAPPENED. THE GASOLINE STENCH WAS SO SEVERE, IN ITSELF, THAT IT MADE MY DAUGHTER SICK TO HER STOMACH, BEFORE THE FUEL STOPPED POURING OUT. PERHAPS THERE ALREADY HAS BEEN A RECALL ON THIS MAKE AND MODEL VEHICLE, WHICH IS A 32 FOOT MOTORHOME. I DO NOT KNOW WHERE TO CHECK TO SEE IF THERE HAS ALREADY BEEN A RECALL. IF YOU HAVE INFORMATION REGARDING SUCH, WOULD APPRECIATE YOU LETTING ME KNOW. THIS PROBLEM NEEDS TO BE CORRECTED AS SOON AS POSSIBLE.
