Two electric connections, one vent line and the pressure line. All need to be disconnected with the tank lifted only a couple of inches. Be sure to push in the pressure disconnect device all the way so it won't nick the o-ring, same for going back together. Do not put any sideways pressure on it. The whole process is just a little pesky. The power connections have the little slip to lock clip that are on the spark plug coils. Not that easy, I use a small pick to just wedge under the lip of the lock tab and then a small screwdriver blade to twist between the two halves to pop them apart. Of course be low on fuel. If not I recommend you syphon some out. Have a spot cleared before hand to put it down.
