My vehicle is producing a strong fuel odor when parked in my garage. So much so, that the fuel odor permeates the entire house. This is a known problem suffered by many C6 owners and is well documented on many Corvette forums and there is even a youtube video (https://youtu.be/P9E3md122mg) revealing the problem. A crack develops in the pressure side of the fuel pump. GM had the exact same problem with several other 2007 model vehicles and promptly ordered a recall because of the potential problem of fire or explosion if exposed to an ignition source......................... sources: Recall: 2007-2009 Chevrolet cobalt / Pontiac G5; 2007 Chevrolet equinox / Pontiac torrent / Saturn ion - fuel pump campaign id #: 12V459000 [NHTSA]....................... GM recalling 40,859 cars for potential fuel leaks [fox news]...................... GM recalling nearly 41,000 vehicles over fuel-leak risk [los angeles times].................... what makes this this potential problem any different from those recalled vehicles. Will it take a death, serious injury or catastrophic loss for these problems to be addressed. I hope not. I think I can speak for all consumers that rely on your Agency to protect us from the shortcomings of manufacturers of faulty products....we need your intervention in this C6 fuel pump problem !!!
The car has developed a terrible gasoline odor. The cause is the faulty plastic fitting at the top of the fuel pump assembly. There is a visible fuel leak running down the tank. The car is not safe and fills with fumes. I cannot park the car inside and fear that the car is dangerous.
Upon parking the vehicle in my garage I noticed a very strong fuel smell emitting from the vehicle. I search all around the car and could not find a leak. This very powerful fuel/gasoline smell would permeate my entire house causing a bit of nausea at times. I started to park the car outside because I was concerned about the possible fire hazard as well as the noxious fumes. I took the car to my local mechanic and they found that the main fuel pump (located in the left side fuel tank) had been leaking from the high pressure side of the pump. The plastic that fuel pump module is composed of started to deteriorate on it's own, and began to spray fuel onto the top of the fuel tank. There is a large skid/support plate that holds up the fuel tank and this plate was retaining a majority of the fuel. This tank is also very close to the exhaust and I'm just fortunate that the fuel did not spray into that direction. After doing some research this is a very common issue with all 2005-2013 Corvettes. So many issues in fact that ac delco (the vendor that supplies the fuel pump modules to GM) has issued 3 updates to this particular part. Here is my oem part number as well as the subsequent update part numbers. My oe pump that leaked: 15785206 (is no longer a good ac delco #) 1st update: 19133441 2nd update: 19302042 3rd update: 19149687.

Strong vapors of raw fuel from vehicle when over 1/2 a tank of gas. Dealer could not locate. Gas leak was on top of tank which was not visible from underneath without removal of rear wheel well. This is documented on Corvette forum as many owners have experienced this issue. It is intermittent and caused by cracking of plastic fitting at top of the tank- appears to be a design defect.
2007 Chevrolet Corvette began smelling of fuel upon fill-up on 8/15/2014. Chevrolet dealer in cary, nc claimed to have diagnosed the issue and charged for diagnostic fee, said end result was faulty fuel cap so it was replaced. Total for this was $42.08. Upon next fill-up, the smell persisted without any change from before diagnosis at Chevrolet dealer. Approximately 7 weeks later, fuel smell had worsened slightly and also the engine was making a "chattering" sound. Since Chevrolet dealer could not determine the fuel smell issue correctly, I chose a highly reputable independent shop and they immediately found the problems. The "chattering" sound was a faulty harmonic balancer, a known issue with the Chevrolet Corvette engines and cost ~$1,100 to repair using Chevrolet parts. The fuel smell was due to a cracked driver side fuel tank (Corvettes use two fuel tanks) which was easily found by this independent shop once the car was lifted. The factory-installed driver side fuel tank had shrunk and cracked, trapping the fuel pump inside, thus forcing the tank and pump to be replaced, along with all related seals and parts. Total to repair these fuel related issues was ~2,700, for a grand total of $3,803.27. Upon performing further research, many Corvette owners have had the exact same problem--driver side fuel tank cracks over time and every online reference found indicates that GM covers the issue. I contacted Chevrolet and was told that I only had a 2-year/24-month warranty on these issues. I find that to be ridiculous, especially since the same issue is occurring on cars of this type across the country. It seems as if Chevrolet and Chevrolet dealers pick and choose who they cover these items for, which is even more ridiculous because I don't think it should be necessary that I have to keep fighting just to be taken care of the way I should have been in the first place.
