Old injectors and lines could be a problem also.

Since nobody else mentioned it yet, I'll talk about the tank return at the back of the engine. That's also rubber hose, just like the ones between the injectors. You may be able to cut it behind the bad spot and reconnect it to the brass part on top of the engine. If it's too short, you can replace the whole rubber part. It fits over a plastic line just a foot or two behind the brass T. I have replaced that before. I carefully sliced it lengthwise to expose the inner plastic line. Then I pulled the old rubber line off, put new rubber line in it's place, and held it to the plastic inner line with a hose clamp. There should be next to no pressure inside the return line so it shouldn't do any leaking after this.
