1993 Honda Civic hose type

I recently noticed a pinhole leak in a coolant/water line/rubber hose that goes to the head/top part of the engine. I don't know what the hose is called but it's only adout 8" long with a 90 degree bend in it. I went to a few auto parts stores and no one has it. A few sales reps offered fuel injection line as a substitute. Would that be okay to use considering the temperature of the water/coolant flowing through there?
