Smell of Gasoline in Chevy TrailBlazer



  • my problem was the gas tank modular assembly. there is a warranty extension on this part if your vehicle has less than i believe 120k.check gm customer service 1-866-790-5600.good luck.
  • On mine it was the fuel pump canister that goes into the top of the tank. It is metal and was rusted out. At the time it was covered under the emissions warranty. I had just under 70K miles. When I 1st detected the odor it was tough to figure out. I thought it was the fuel cap which I replaced with no effect. After about 3 weeks I began to see a puddle of gas under the vehicle.
