2000 Subaru Outback Fuel System Problems

Your 2000 Subaru Outback may develop a strong fuel smell inside the cabin during cold weather (around 30°F and below), forcing you to drive with windows open until the smell clears. A dealer identified the likely cause as deteriorated fuel lines and fittings on the top right side of the engine that need replacement. The repair typically costs around $200 or slightly more and involves replacing the fuel lines and screw clamps.

When it's cold outside and you have your climate control set to fresh air, gasoline smell enters your car's cabin. This appears to be caused by a fuel line leak that only happens during cold weather. The repair will likely involve inspecting and replacing the affected fuel line or seals that become brittle or crack in freezing temperatures.

You noticed a gas smell inside your car in September 2013. Your dealer replaced the fuel pump gasket, then the fuel pump itself in October, and replaced the fuel pump again in November — but the gas smell persists, though it's weaker. The underlying cause of the persistent odor needs to be identified and addressed, which may involve inspecting the fuel system components for leaks or damage.

FUEL LEAK SOMEWHERE IN ENGINE COMPARTMENT; GASOLINE ODOR WENT INTO PASSENGER COMPARTMENT. WORSE IN VERY COLD OR VERY HOT WEATHER. IT'S BEEN LIKE THIS FOR 3 OR 4 YEARS. MY MECHANIC SAID IT WOULD COST $200 TO TRY TO FIND THE LEAKS -- MAYBE SOME HOSE CLAMPS NEAR THE FUEL INJECTORS ARE THE CULPRIT, BUT ARE HARD TO GET TO WITHOUT TAKING APART SOME OF THE ENGINE? I'VE SEEN MANY SIMILAR COMPLAINTS ON VARIOUS ONLINE BULLETIN BOARDS. I SUPPOSE NHTSA WON'T FORCE SUBARU TO ISSUE A RECALL UNTIL SOME LARGE NUMBER OF DRIVERS/PASSENGERS DIE FROM AN ENGINE FIRE THAT STARTS FROM THIS TYPE OF LEAKING. MOST RECENT INCIDENT: LATE JANUARY, 2010. *TR

A VERY BAD FUEL SMELL INSIDE CABIN WHEN IT'S COLD OUTSIDE AND THE VEHICLE IS WARMING UP AND THE VENT IS RUNNING. FUEL LEAK UP BY FUEL FILTER AREA. CHECKED ALL HOSES AND CLAMPS NO LEAKS. DEALER CHECKED IT OUT AND COULDN'T FIND A LEAK OR PROBLEM. AFRAID THIS MAY START A ENGINE FIRE SOMETIME. *TR

THERE IS A FUEL LEAK IN THE ENGINE COMPARTMENT OF MY SUBARU OUTBACK WAGON ON COLD DAYS AND IS A POTENTIAL FIRE HAZARD. I HAVE TALKED TO SEVERAL OTHER PEOPLE AND THEY HAVE THE SAME PROBLEM. I WOULD THINK THERE WOULD BE A RECALL SINCE IT IS FUEL RELATED AND A SERIOUS RISK. THE FUEL LEAKS FROM A RUBBER HOSE ON THE LEFT SIDE OF THE ENGINE THAT CONNECTS TWO HARD GAS LINES. I TRIED TIGHTENING THE CLAMPS AND IT DID NOT HAVE MUCH AFFECT. THE HOUSE HAS NO HOLES OR TEARS IN IT. NEITHER DO THE HARD GAS LINES. SO I DON'T KNOW IF IT CANT HOLD THE PRESSURE OR WHAT? I NOTICED IT AFTER DRIVING FOR A FEW MILES. I STOPPED FOR A MINUTE AND GOT A STRONG GAS SMELL. THERE WAS GAS IN THE ENGINE COMPARTMENT WHEN I CHECKED IT WHEN I GOT HOME. I DROVE A TOTAL OF TEN MILES MAYBE. *TR

STRONG SMELL OF GAS IN THE CABIN OF THE VEHICLE DURING COLD WEATHER - DEFINITELY SMELLS OF LEAKING GAS - DEALER ADVISED AND LOOKED AT CAR A NUMBER OF TIMES - COULD NOT RESOLVE. I GAVE THIS CAR TO MY DAUGHTER AND I FEAR AN ENGINE FIRE. *TR
