NHTSA Complaint #10909455 — 1997 VOLVO 850

SIMILAR TO NHTSA ID NUMBER: 10365806. WHEN FUEL TANK IS FILLED COMPLETELY, THERE IS A STRONG ODOR OF FUEL OUTSIDE THE VEHICLE AND SOME FUEL ODOR IN THE TRUNK. NO ODOR WHEN TANK IS ONLY PARTIALLY FULL, E.G., 80% FULL. ODOR NOTICED WHEN VEHICLE STATIONARY. NO ODOR IN PASSENGER COMPARTMENT. ISSUE ONGOING FOR ROUGHLY LAST 7 YEARS (NOT SURE). NO DRIPPING FUEL OBSERVED. LEAK MAY BE AT FUEL PUMP QUICK-DISCONNECT FITTINGS. LEAK MAY HAVE STARTED AS A RESULT OF EVAP SYSTEM REPAIR IN LATE 2009--NOT SURE. DEALER CLAIMED TO HAVE FIXED LEAK AT FUEL PUMP FITTINGS IN 2011, BUT ODOR ISSUE PERSISTS IF TANK COMPLETELY FULL. NO CHECK ENGINE LIGHT ISSUES SINCE 2011. I AVOID FILLING TANK COMPLETELY TO AVOID ODOR. IF I INADVERTENTLY FILL TANK COMPLETELY, ODOR RETURNS. "WHEN DID THIS HAPPEN" DATE I ENTERED IS JUST A ROUGH GUESS OF WHEN THE ISSUE STARTED. VEHICLE IS STORED OUTDOORS AND DRIVEN INFREQUENTLY, ~ ONCE PER WEEK AVERAGE. ODOR IS EASILY NOTICEABLE OUTDOORS WHEN TANK IS COMPLETELY FULL.
