We don't need to tell you why a leaky fuel tank can be a big hazard. Something about flammable liquid seeping out from underneath a car raises a huge red flag, and now the National Highway Traffic Safety Administration is investigating 33,000 2004 model year Chevrolet Corvettes over this very issue. According to The Detroit News, NHTSA has received 30 complaints from owners claiming that either liquid fuel or fuel vapor has been leaking from a tank.

Alan Adler, a spokesperson for GM, says that the automaker isn't aware of any injuries or accidents resulting from this problem. Furthermore, GM plans to fully cooperate with NHTSA on this investigation in order to promptly resolve the problem. In 12 of the 30 complaints filed with NHTSA, a fuel tank was replaced or identified as the source of the leak, and we assume that a quick recall will be in order to prevent further instances.

      I have a 2004 c5 with fuel problems, when the tank is half full or more i smell gas . Do i need both tanks replaced?

      Wasn't that the same tank that made all Corvettes switch to run-flat tires? (there was no room for the tank anywhere but the spare tire well)
        • 4 Years Ago
        No, there's a spare tire well in the C5s. In the mid east it shipped with a spare. The spare was removed for weight, cost and trunk space concerns.

        The C6 removed the spare tire well I think.

        Imagine if the spare was were the C5 gas tanks were! You'd have a heck of a time getting it out of the trunk if you needed it, since it'd be more than an arm's reach from the trunk opening (rear).

        And in the C6, the well was removed in order to relocate the mufflers, not the fuel tanks.

        (Plural, because there are two fuel tanks in C5 and C6 Corvettes.)

      Hmm... I have 2 C5s and haven't had this issue. Heard of it a bit but didn't know it was even close to widespread.

      I doubt we'll see a recall over 30 fuel tanks. More like an inspection campaign.

      In before cries of government motors and bwah from butt hurt toyota fans that screaming for a billion dollar fine.

      C5's have two tanks, sort of straddling the drive shaft. A sensor and pump makes sure the tanks' level is balanced at all times (for better handling, of course).

      The transverse mufflers with mid-rear exhaust exit, and independent rear suspension arrangement, seem to be in the way of where the spare tire used to be (in C4's).

      Eliminating the spare did add to the overall weight reduction of the C5's, bringing it to approx. 3200 lbs.

      leaky fuel tanks
      roofs that blow off
      uncomfortable seats
      plastic interiors
      ...
      ...

      That's what you get when you buy a sports car that is 1/2 the cost of it's competitors.

      I have a 2004 c5, I smell gas everytime the gas tank is more than half full. Do both tanks need to be replace?
      • 4 Years Ago
      This is nothing new. GM has had fuel tank leaking problems on the Vette since it the C5 came out in 1997. The issue is the car has dual fuel tanks and the fuel modules are installed in the side of the tanks instead of the top. As they investigate this deal they will find numerous internal PI’s and bulletins’ on this subject. GM always blamed a dealer technician for over torqueing the fuel module screws even though virgin cars had fuel leaks as well.
