I am thoroughly confused. Is the screen inside the tank or not? I have a 1987 300TD Turbo wagon, and the pics here do not match up to my car. These pics look like the screen is in the chasis of the car. My fuel tank is external, right in front of the rear muffler, and is held in place by 6 -8 bolts.

I am removing the fuel tank today to find a leak, and want to change the screen while I have the tank out.
