I've replaced a ton of them both here and Iraq, I use a 3/8 drive 11/16 crows foot wrench and a long extention, and pull all lines before pulling the pump. The crows foot will also allow you to torque them to spec on reinstallation if you choose to. If you have a real stubborn one they also make crows foot line wrenches to.
