Get a rebuild kit for the throttle body. Be sure to get the rebuild kit for the fuel presure regulator. This is probably your leak. Most quality kits come with good instructions! Get new o-rings for fuel lines if they don't come with either kit.

Well it sounds like the leak is at the right rear of the engine as you face it if so right back by the fire wall is where the fuel lines couple together if you take the lines apart there should be a o-ring on eack line check that out and see if that is where the leak is

Instructions
  1. Raise the hood of the Kia Shortage view the interior. From front to back you will see the grill, the radiator, the radiator fans, and the engine. On the top of the engine is the valve cover---an aluminum cover that encloses the top of the engine---that is bolted in place.
  2. Look behind the valve cover for an aluminum rail that goes across the back of the engine. Inserted at equal distances---both below and into the rail---are tubular injectors that are also inserted into the engine. The aluminum rail is called the fuel rail. It is a hollow tube that holds the tops of the injectors and supplies them with fuel. Each of the injectors are also plugged into the engine wiring harness.
  3. Inspect the injectors for any signs of fuel leaks. Although rare, leaks do occur, especially due to age and mileage. If leaking, do not drive the car as there is an increased risk of fire. Repair the injector seals before driving the car again.

How to replace injectors 1990 corvette



REMOVAL & INSTALLATION

See Figures 1, 2, 3 and 4
Before performing any service on the front or rear TBI unit, you must place the unit in a suitable holding fixture such as J-9789-118, BT-30-15, or equivalent. If you dont place the unit in a suitable fixture, the throttle valve may be damaged.

  1. Disconnect the negative battery cable.
  2. Remove the TBI unit from the vehicle, and place it in a suitable holding fixture.
  3. Remove the fuel meter cover, as follows:
    1. Remove the 5 fuel meter cover attaching screws and lockwashers.




0900c1528008fe62.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: Exploded view of the fuel meter cover attachment

  1. Lift off the fuel meter cover with the fuel pressure regulator (rear unit) or accumulator (front unit), noting their positions for reassembly.
  2. Remove and discard the fuel outlet passage only. Leave the fuel meter cover gasket on the fuel meter body.


CAUTION Do NOT remove the 4 screws securing the fuel pressure regulator or accumulator to the fuel meter cover. The regulator or accumulator includes a large spring under heavy compression which, if accidentally released, could cause personal injury. The fuel meter cover is serviced as a complete assembly only. On the rear unit, the fuel meter cover includes the fuel pressure regulator which was calibrated and plugged at the factory.


0900c1528008fe63.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 2: Bottom view of the front and rear fuel meter covers
Do not immerse the fuel meter cover (with the pressure regulator or accumulator) in any type of cleaner. Immersion will damage the internal diaphragms and gaskets.

  1. Remove the foam pressure regulator sealing ring (dust seal) from the rear throttle body.

When removing the injector, be careful to avoid damaging the electrical terminals on top of the injector, injector fuel filter and nozzle. Do NOT use pliers to remove the injector, as this could cause damage. The injector cannot be disassembled and is serviced as a complete assembly only. As it is an electrical component, it should not be submerged in any type of cleaner.
  1. With the fuel meter cover gasket in place to protect the casting, use a suitable prytool and a fulcrum, as shown in the accompanying figure, to carefully lift the injector until to is free from the fuel meter body.

Fig. Fig. 3: Carefully pry the fuel injector out of the fuel meter body

  1. Remove the injector. If removing both injectors, make sure to mark them front and rear, so they can be reinstalled in the proper position. The injectors are NOT interchangeable and cannot be switched during installation.
  2. Carefully rotate the injector fuel filter back and forth, then remove the filter from the base of the injector.
  3. Remove and discard the fuel meter cover gasket.
  4. Remove the large O-ring and steel back-up washer in the top counterbore of the fuel meter body injector cavity. Remove the small O-ring located at the bottom of the injector cavity.

Exploded view of the fuel rail and injector mounting


Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
  1. Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
  2. Properly relieve the fuel system pressure and disconnect the negative battery cable.
  3. Remove the air intake duct, as necessary for access.
  4. Tag and disengage the fuel injector electrical connectors.
  5. Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
  6. Loosen and remove the fuel rail retaining bolts.
  7. If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
  8. Carefully lift the fuel rail assembly and fuel injectors from the intake.
  9. Carefully release and separate the fuel injectors from the rail assembly.
  10. Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
To install:
  1. Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
  2. Install the injectors to the fuel rail assembly.
  3. Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
  4. Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
  5. If removed, connect the fuel lines to the rail assembly and secure the fittings.
  6. Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
  7. Engage the injector electrical connectors.
  8. Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
  9. Install the air intake duct.
