DUAL FUEL TANK CROSSFLOW/LEAKAGE Defect Investigation for the 1990 F450
Vehicle Component: Vehicle Speed Control:Linkages*
Summary: On July 14, 1993 Ford filed a defect information report concerning fuel tank cross flow leakage on F-series light trucks and cab chassis built from July 22, 1989 through December 17, 1992. The remedy was to replace the fuel pressure regulator and install a check valve between each fuel supply line and fuel tank (2) to repair the supply side fuel cross flow problem (recall 93V-125). ODI opened RQ98-008 on May 29, 1998 because of the large number of alleged remedy failures and reports of fuel cross flow on 1993 model year vehicles built after December 17, 1992. Fifty three percent of the ODI reports occurred during 1998-1999 and reveal an increasing trend for the past four years. The subject vehicles can experience fuel transfer from one tank to the other due to malfunctions in the fuel system. When fuel is pumped or returned to the non-operating tank (cross flow), the capacity of the non-operating tank can be exceeded, causing fuel to overflow past the filler cap, creating a fire potential.
