The swivel or non-swivel ratcheting wrenches are a must for this...A piece of clear flexible hardware store tubing with the little hex hold nut pushed into one end of a foot long section will get the nut started (a poor mans u-joint..I saw a helicopter mechanic do this)...always good to have a light colored towel under the plugs just in case (The Abyss)....If you do it like this a couple of times....no need to take the lines off...Got a new Lowes home center right across the street....that speeded things up ...
