Is there an adaptor that connects to the black fuel line, to the left, in the picture so I can connect it to a rubber hose? I would prefer not to cut it. It is the line that goes from the fuel pump assembly to the front of the car.

If there isn't an adaptor, what is the best way connect the rubber hose to the fuel line going forward to the engine?

 

I can lathe you a custom one if you can deal with it not shipping until Wednesday. One end simulating the stock fuel pump quick-connect that will interface that stock feed line, and one end with a hose barb for connecting a 5/16 fuel hose. PM me if you want to go that route.
