The concern apparently centers around the fuel delivery system, which initially prompted a recall back in 1997. The original repair should have corrected the issue, but if the “independent automobile repair facilities” that performed the service on many of the cars didn’t properly install the new screw clamps, they could have damaged the fuel hoses, which in turn could cause smoke or even an engine fire. New fuel divider blocks should (hopefully) fix the issue this time around, which affects some 2,356 F355s and F355 F1s manufactured between 1995 and 1999. Full details in the recall notice at NHTSA.
