    I smell gas in my 95 concours

    I've noticed that my 95 concours smells like gas under the hood after driving it. It also smells like gas in the car when I have the heater/AC on and I'm idling at a stop light. Anyone know what's going on?

    Any visible fuel leaks under the car? If not, I would suspect the EVAP system. This is the system that captures fuel vapors from the gas tank. A hose may have come off, or there may be a problem with the charcoal canister.

    Thanks for the reply! No I haven't noticed any leaks. Would the hose be visible from the top? And what/where is the charcoal canister?

    Hmm. here's the tough part. They got pretty good at hiding those canisters, but i know of a few locations. Look for a black plastic brick underneath the car, in front of the gas tank. Also, see if the gas smell gets stronger underneath the car.

    Thanks! I'll give that a try and get back to you.

    Uhhmm...stop what you are doing and check for leaking plastic fuel lines at the injectors. Starting to see that quite a bit.

    This is what we are concerned about....the leaking fuel lines Nhtsa is looking in to.....

    NHTSA Action Number : PE03050 NHTSA Recall Campaign Number : N/A
    Make : CADILLAC Model: SEVILLE
    Manufacturer : GENERAL MOTORS CORP. Year : 1997
    Component : FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:FUEL RAIL
    Date Investigation Opened : October 30, 2003
    Date Investigation Closed : Open
    Summary:
    ODI HAS RECEIVED 69 COMPLAINTS ALLEGING UNDERHOOD FUEL LEAKAGE IN THE SUBJECT VEHICLES, INCLUDING 6 FIRES. APPROXIMATELY TWO-THIRDS OF THE COMPLAINTS IDENTIFY THE FUEL RAIL AS THE SOURCE OF THE LEAKAGE. MANY OF THE COMPLAINTS DESCRIBE FUEL SPRAYING FROM SMALL HOLES IN PLASTIC SECTIONS OF THE FUEL RAIL ASSEMBLY. THE OLDSMOBILE AURORA VEHICLES ARE EQUIPPED WITH A 4.0L V-8 ENGINE AND THE CADILLAC MODELS ARE EQUIPPED WITH NORTHSTAR 4.6L V-8 ENGINES. THE VEHICLES ALL USE A COMMON FUEL RAIL. APPROXIMATELY TWO-THIRDS OF THE COMPLAINTS HAVE BEEN RECEIVED IN THE LAST TWO YEARS.

    The document shows a '97 Seville. Basically its the same engine.

    There is no need to complain. The '95 - '97 have been recalled. Just go to the dealer (SOON) and they will replace the fuel rail with a stainless steel rail free of charge.
