Close-up of bottom, drain plug to the left. When the tank is in the vehicle the plug is to the right of the feed/return lines when looking up from under the vehicle. There is only one way to get to the lines, get under the vehicle from the drivers side, back far enough to view over the top of the differential. You'll see the fuel lines, each with their respective retaining clips. Reach up and turn the clips counter clock-wise a quarter turn. DON'T YANK THEM OUT!!! Leave them attached to the tank.
