If it's the rubber hose leaking just above the injector, that is quite common on those engines. It is fairly easy to replace them with pieces cut from standard fuel hose. Make certain the new hose stock is good to a fairly high pressure, in case the pressure regulator went bad they wouldn't burst and spray your engine with fuel.

As I recall, removing the old hoses requires some sort of cutting-off of the metal hose collars, but it's not a big deal.

Replace the hose to the cold start injector and the two hoses between the regulator and the fuel rail at the same time.

You'll need to buy a few hose clamps also.
