9600 Ford fuel leak

[jhp123]

I have a 1975 9600 with six cylinder diesel. Fuel is coming out of the fuel injector on the side up against the motor. I can't see exactly where it's coming from. it doesn't leak while idling, but it begins to leak in a small stream coming from the engine side of the pump when the engine is revved up. what's the most likely problem?

could be return line, injector line or injector

I'm a bit confused. Is it leaking at the injector or the injection pump?

Sorry dt86, i can see where i wasn't clear. It is NOT leaking out of the injector lines coming off the pump or the injectors. It appears to be leaking from the side of the injector pump that you can't see.(engine side). Could not get a good visual on it. Was hoping to get an idea before i tried to take the pump off, of what is on that side that would leak with a steady rate once throttle is increased from idle. thank you for the help
