* Relieve the fuel system pressure * Disconnect the negative battery cable if car is equipped with Delco-Loc 2 or Theftlock audio system make sure you got the activation code first * Remove the fuel tank Disconnect the fuel pump/sending unit harness connector and the fuel tank pressure sensor from the fuel tank * The fuel pump/sending unit assembly is located inside the fuel tank.Using a pair of snap-ring pliers contract the retaining collar and remove the top of the fuel pump assembly * Lift the fuel pump/sending unit assembly from the fuel tank * Inspect the condition of the O-ring around the opening of the tank if its dried,cracked or deteriorated replace it * Remove the strainer from the lower end of the fuel pump.If its dirty,clean it with a suitable solvent and blow it out with compressed air.if too dirty replace it * Remove the fuel pressure sensor mounting bolts and separate the sensor from the top of the fuel pump assembly * If it is necessary to separate the fuel pump and sending unit,disconnect the electrical connectors at the pump,noting their postions * Disconnect the fuel line from the pump
