Remove the leaky lines, look closely at both mating surfaces. If the inverted flares on the lines and or the flared fittings on the injector pump are scored, polish them up with some fine Emory cloth and finish of with some green scotch brite pad. Hold the abrasive in one hand and use a twisting motion on the other hand holding the inverted flare or the pump flared fitting. Don't go crazy with it you just want to polish the metal to remove the scoring between the two mating surfaces. Clean the line by dripping some isopropyl alcohol into it and blowing out with compressed air. Repeat twice before reinstalling the lines. Also do the same to clean the pump flare fittings. Torque the flared fittings to the pump with thread sealant. Torque the lines to the fittings on the pump and the injectors but don't go all gorilla on them. And make sure to reinstall the gang clamps with the rubber isolators. They prevent the lines from cracking due to metal fatigue caused by engine vibration. That will do the trick and remember if fuel can get out, then when you shut the engine off, and it cools down, air can also get in through the same path. Later fellas
