What to do about bad fuel filter on Jeep Grand Cherokee?
Repairing them means getting under the vehicle and disconnecting steel fittings. It really still isn’t that difficult to deal with, as long as you give the vehicle a few minutes for the fuel pressure to go down.

Fuel injector is mounted in throttle body so that fuel is injected into incoming airflow. When injector solenoid is energized, armature and plunger move upward against spring. Check ball above injector nozzle moves off seat and opens small orifice at end of injector.
Where is the idle switch on a jeep?
TPS is mounted on throttle body assembly. WOT switch provides an input signal to ECU when engine is at wide open throttle. The ECU enriches air/fuel mixture. The WOT switch is located on the side of throttle body. Idle switch is integral with ISA motor and provides voltage signal to ECU.
Is the fuel regulator part of the throttle body?
Fuel pressure regulator is integral part of throttle body. Pressure regulator has a spring chamber that is vented to same pressure as tip of injector. Because differential pressure between injector nozzle and spring chamber is same, only the length of time that injector is energized controls volume of fuel injected.
