Re: TO IDENTIFY PART ON '93 FORD 302 EFI V-8 USING...
Sounds like it is the tube to part of your emissions equipment. It usually goes to another hose that goes to a one way valve from the air pump for the air injection for your exhaust gas recirculation system. These are prone rust and can be purchased from Ford for replacement.

Well basically, you remove the intake plenum and replace the gasket and reinstall the plenum. Here are the steps:
1. Disconnect the negative battery cable from the remote jumper terminal located at the right strut tower. 2. Remove the air inlet resonator and tube. 3. Remove the throttle actuator cables from the throttle arm and bracket. 4. Disconnect Secondary Runner Valve (SRV), Manifold Tuning Valve (MTV), Throttle Position Sensor (TPS), Idle Air Control (IAC) motor electrical connectors. 5. Remove the electrical connector and the Intake Air Temperature/Manifold Absolute Pressure (TMAP) sensor. 6. Disconnect vacuum hoses from the Secondary Runner Valve (SRV) reservoir, Speed Control reservoir, and PCV. 7. Remove right and left intake manifold supports. 8. Remove support brackets at the intake manifold front corners and MTV. 9. Loosen upper fastener attaching throttle body to support bracket. 10. Remove clips attaching EGR tubes to intake manifold. 11. Remove intake manifold bolts and manifold 12. Remove old gaskets, Clean gasket surfaces, and install new gaskets. 13. Reverse steps to reinstall manifold
On1995 Ford Truck Bronco 5.8L EFI 8cyl the Control Module-Ignition is located under hood, center, upper engine area, front of intake manifold, mounted on front side of distributor.

Fig. 4: Exploded view of the EGR system and related components for the 4.0L engine (click over pic for zoom) REMOVAL & INSTALLATION
PFE/DPFE Sensor This component is found on all engines, and is also referred to as the backpressure transducer.
Disconnect the negative battery cable.
Detach and label the wiring harness connector from the PFE/DPFE sensor.
Disconnect all of the hoses from the sensor.
Remove the mounting nuts, then separate the sensor from the mounting bracket.
If necessary, remove the EVR solenoid and the PFE/DPFE mounting bracket from the upper intake manifold.
To install:
If removed, install the EVR solenoid and mounting bracket onto the upper intake manifold.
If applicable, install the EGR tube heat shield.
Position the PFE/DPFE sensor on the mounting bracket, then install and tighten the mounting nuts until snug.
Attach all necessary hoses and wiring to the sensor.
Connect the negative battery cable.
EGR Vacuum Regulator (EVR) Solenoid The EVR solenoid is mounted either on the same bracket as the
PFE/DPFE sensor, attached to the upper intake manifold, or near the EGR
valve on its own bracket.
Disconnect the negative battery cable.
Label and detach the wiring harness connector from the EVR solenoid.
Detach the main emission vacuum control connector from the solenoid.
Remove the retaining nuts, then separate the solenoid from the mounting bracket.
To install:
Position the solenoid on its mounting bracket and install the retaining nuts.
Attach the main emission vacuum control connector and the wiring harness connector to the EVR solenoid.
Connect the negative battery cable.
EGR Valve See Figures 6 and 7
Disconnect the negative battery cable.
If necessary, remove the air inlet tube from the throttle body and air cleaner housing.
Label and detach all vacuum hoses from the EGR valve.
Label and detach any electrical wiring harness connectors from the EGR valve.
Disconnect the EGR valve-to-exhaust manifold tube from the EGR valve.
Remove the EGR valve mounting fasteners, then separate the valve from the upper intake manifold.
Remove and discard the old EGR valve gasket, and clean the gasket mating surfaces on the valve and the intake manifold.
Fig. 6: Cutaway view of a base entry type EGR valve
Fig. 7: Cutaway view of a side entry type EGR valve To install:
Install the EGR valve, along with a new gasket, on the upper
intake manifold, then install and tighten the mounting bolts to 4-22 ft.
lbs. (20-30 Nm) on 3.8L engines, or to 106-49 inch lbs. (1-18 Nm) on
5.0L engines.
Connect the EGR valve-to-exhaust manifold tube to the valve, then tighten the tube nut to 30 ft. lbs. (41 Nm).
Connect all wiring or hoses to the EGR valve.
Install the air inlet tube.
Connect the negative battery cable.
Hope this helps, good luck (remember to rate this comments).

Exploded View of the Starter Motor Mounting Components
CAUTION: When servicing the starter motor or performing other underhood work in the vicinity of the starter motor (11002), be aware that the heavy gauge battery input lead at the starter solenoid is "electrically hot" at all times. A protective cap or boot is provided over this terminal (B-terminal) on all carlines and must be replaced after servicing. Be sure to disconnect the battery ground cable before servicing the starter motor.
Disconnect the battery ground cable (14301).
Remove the air cleaner (ACL) and the air cleaner to intake manifold tube (9B697). Refer to Section 03-12A for the procedures.
Remove the two upper starter motor bolts.
Raise and support the vehicle.
Remove the intake manifold support bolts and the intake manifold support (9J444).
Disconnect the S-terminal wire.
Remove the B-terminal wire nut and disconnect the B-terminal wire.
there is a coolent tube runing under the lower intake manifold it will leak or bust open it comes right out the back in the water delivery unit get you book and pull the upper manifold and you should be able to see the problem if it is pull the lower and repair the tube.
