I think the "Black Box" that you are inquiring about is the Fuel-Tank. There are five hoses that travel to the Fuel-Tank. Two of the hoses are the fuel filler liquid line and the fuel vapor line. They travel from the fuel filler neck, to the fuel-tank. The other three hoses travel from the top of the fuel-Tank (at the fuel sending unit) and run along the underside of the car and over to the engine. One hose is the fuel supply line, one is the fuel return line, and the other is the vapor line (part of the EVAP system). The hose that is leaking is probably your fuel supply line. I suggest this because your fuel-pump is inside the fuel-tank. This is an older car, be prepared for the worst. You may need a fuel tank, fuel-lines, sending unit, and a fuel-pump. If you go to a shop to have this repair done. they are going to recommend replacing parts that are old. This is because they don't last forever and you don't want to have to do the job twice. Even if the pump and sending unit are working, if you can aford it and your going to hold onto the car for a while, replace them. I hope that is what you were looking for. If you have other questions please feel free to write back. good luck.
Am working on the same problem. Have narrowed it down to a couple of things. The primer curcuit on my '88 is not work off the computer it will not prime the fuel system. Have found away around that by putting in a new relay off the starter line. The main problem though is that the check valve in the fuel pump is shot and allows all the fuel to drain back into the tank. It takes too much time to get the fuel preasure up if the fuel system is completely empty. Am going to replace the fuel pump and see what happens. The fuel pump relay is located under the glove box, have not found diagram map of the relays there, there are 10 there. If you need a wiring diagram for your car, go to autozone, can print off a wiring diagram there. Good luck.
The easiest way to disconnect it is to remove the fuse for security system. You can find the fuse box, under the steering wheel. Remove the plastic cover, and look on the back for the diagram to see which fuse to take out.
On the end of the fuel lines where it plugs into the fuel pump, there is a little plastic clip in the end of the hose squees the clips together and pull out fuel line from pump, do the same with other one
The fuel pump is located inside the fuel tank. You will have to pull the tank, so get out any esscess fuel you can. Undo the battery, red cable first, Jack up the rear of the car and support it on jack stands high enough to pull the tank down and out the rear. Disconect any rubber hangers at the rear of the exhaust. Disconect the filler hoses from the tank. Disconect the fuel lines, you may have to have a special tool to dosconect the fuel lines, ck at your local parts store for any you may need. Support the tank with a floor jack and remove the retaining bolts/straps. Lower the tank and disconect any wiring from the sending/pump location. Pull the tank down and out the rear. The fuel pump is held in with a loc-ring, you can use a screw driver to turn half way to remove, then the assy. will come out. this is a 2 person job on the ground, and be careful.
