Do a dry layout off the car making sure you have all the right parts, connectors, washers and seals. As you need to drop the axle to take the tank out the first step would be loads of penetrating oil on the axle studs/nuts, applying once a day for a few days. Clean up the stud threads using a spare nut before attempting to undo them. It would also help to use up your fuel to save time draining the tank. Then start from the tank and work your way forwards. Are you using flexi lines or pre-shaped ones?
