Truck Repair: Quick Question, kind folks, rubber hose

Question
Hello Kind Folks,
           I have a 1970 Ford 3/4 ton pick-up and the brake line that goes from the motor to the front passenger wheel appears to have a slit/cut/leak in it.It doesn't look to hard to replace,but I am certainly no mechanic.Can anybody tell me anything or maybe point me to a website that might have a diagram that could show me how to take care of this type of problem?Also,would I have to bleed all the brakes when I do this,which I have never blead brakes before.Any help would be greatly appreciated.
                   Sincerely,
                   Skyler


Answer
replace the line. leave its fitting, and clamps loose  at the bottom where it meets the rubber hose, so that there is no downhill runs, basically a gradual descent to the rubber hose. fill it with fluid and wait till you get a stream of fluid at the open end there, tighten it up. fasten down the line, what tiny amount of air remains should work out shortly.
