You should remove the fuel pressure test port (schrader valve) cap from the fuel injector rail while keeping power steering pipes attached and position the Power Steering Pump in front of the timing chain cover. The generator removal process starts with placing the electrical harness aside from the right fender well retainer and then removing the generator from the vehicle. Add the generator into the vehicle above the drive axle then connect the electrical harness to its retainer installed on the right fender well.
