Fuel system Vehicle recall #90V015000 · 1990 · 68 vehicles
What's wrong: On c and k models, feed and or return fuel lines can contact the automatic transmission shift linkage cordon shaft. In addition, on k models lines May also contact front propshaft. In either case the fuel lines could be damaged resulting in a fuel leak.
Why it matters: A hole could be rubbed through these fuel lines, allowing fuel leakage near exhaust crossover pipe; this could result in an engine compartment fire that could spread to the passenger compartment.
The fix: Install newly designed fuel line routing bracket to prevent contact and, if necessary, replace fuel lines.
Brakes (hydraulic) Vehicle recall #90V108000 · 1990 · 1,962 vehicles
What's wrong: Loose pivot bolt holding the brake pedal to its support bracket could disengage from the nut.
Why it matters: This could cause loss of braking activity that couldresult in a truck crash without prior warning.
The fix: Retorque brake pedal pivot bolts to specifications to prevent loosening.
Transmission & drivetrain Vehicle recall #93V016000 · 1993 · 1,702,880 vehicles
What's wrong: Unanticipated heat in the transmission can force the transmission fluid out of the vent tube.
