I have a 97 900s, autotragic...being auto dosen't bother me as much as the 22mpg it gets. I have notice the mpgs dropping by X% for two months. I have use a fuel system cleaner and drive it in a fashion that not even the girlfriend complains about.
But the milage is still dropping. Is dropping the fuel tank the only way to get to the fuel filter? what else could help out this "pump pig"?
