Hi, If the leak is from the Large nut that goes into the pump, Yes, it's either loose or needing a copper / felt washer, if its the pipe you will have to replace, I would go for the Nut being loose, SAFTEY IN MIND put the car on ramps, put in 1st / reverse, handbrake, chock the rear wheels & inspect where the leak is coming from, If from the Nut's you will have to drain the system otherwise the oil will be lost, to bleed, fill up the reservoir, then steer to the Left / Right, Left / right, check the level, check for leaks if none, job done.
