It's not all that bad to replace. There is a banjo connection onto the pump and a compression fitting on the other end of the loop (under the PS pump/close to the PS pressure sensor)
- big socket, u-joint, extensions, breaker bar/ratchet for the banjo
- flare wrench for the compression fitting. An open-end wrench or vise grips could work, but like brake lines, very likely to strip without the flare wrench.
