1994 GMC S15 recalls 2
Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- The fuel tank filler pipes were not manufactured to specification which caused loss of fuel between the fuel tank filler pipe and the vent tube during a test. The loss of fuel was in excess of the amount permitted by fmvss no. 301, "Fuel system integrity."
- The risk
- Consequence of non-compliance: if a vehicle crash were to occur, it may cause the joint between the fuel tank filler pipes and the vent tube to crack. If the vehicle overturned, fuel leakage would occur, which could result in a post-crash fire.
- The fix
- Dealers will replace the fuel filler pipe on these vehicles.
