92 940 turbo w/220K miles. Main fuel pump and filter replaced at approx 120K miles as a preventative measure. Recently began stumbling when fuel is low (when less than 2-3 gal left in tank) and car is cornering, most notably when cornering to the right. Replaced in-tank pump and sock, and replaced fuel tank cap, but the problem continues. After refueling the stumbling stops. Otherwise the car seems to perform fine.
