Those V8's have a 28-30 psi high-pressure EFI system... check for your fuel lines' wear, age, dry-rotting, leaks, and secured fit/connections.
If there is anything abnormal & leaks while the engine is running & hot... then be ready with a fire extinguisher, just in case.

Yes, the D-Jetronic system uses hose top injectors and also quite a few hoses in the fuel cicuit on top of the engine. These hoses should be inspected and retightened regularly and replaced before they start leaking due to age. Yours may have already been replaced given the overall good condition of your car but you should at least inspect them (As you had your injetors checked ask the guys if they replaced the hoses or if they were in good shape). If they have been replaced recently or if you replace them do not forget to retighten them regularly at the beginning (no need to squish them completely though).

I always have a multipurpose blanket in my trunk that I can also use to choke a fire. If you ever feel something is on fire under the hood cut the contact immediately as this will stop the pump from sending fuel at high pressure on the fire. Also beware that if and when you open the hood this will bring additional air to the fire and you may end up with big flames. This is where a blanket is handy but you must have it ready before opening the hood. An extinguisher is of course the safest device but it damages your engine bay quite as much as the fire itself. That foam is extremely corrosive.
