- Service brakes, hydraulic › Power assist › Vacuum › Hoses, lines/piping, and fittingsCovers: GMC S15 1994, Chevrolet S10 1994
Reported issue: A vacuum hose can detach from the power brake booster check valve as a result of engine backfire.
Possible consequence: This can result in increased engine idle and loss of power brake assist after depletion of the booster vacuum reserve.
Remedy: Dealers will install a clamp on the power brake booster assist.
- Fuel system, gasoline › Storage › Tank assembly › Filler pipe and capCovers: GMC S15 1994, Chevrolet S10 1994
Reported issue: 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."
Possible consequence: 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.
Remedy: Dealers will replace the fuel filler pipe on these vehicles.
