| Diesel Fuel System problems |
The contact owns a 2008 Ford F-250 equipped with a 6. 4l diesel engine. While driving at an undisclosed speed, the vehicle experienced a catastrophic fuel system failure. The vehicle was towed to an independent mechanic, where the technicians diagnosed the issue as gasoline contamination in the diesel fuel, which destroyed the high-pressure fuel pump. The vehicle was subsequently taken to an authorized Ford dealer for the repair. Shortly after the initial repair was completed, approximately 15 minutes away from the dealer while driving 45 mph the vehicle shut off. The vehicle lost engine power, power steering, braking assistance, and electrical systems failure. The vehicle was towed back to the dealer. The contact stated that the dealer replaced the fuel pump, choosing not to follow Ford manufacturer guidelines to replace the diesel tank, despite the tank having two fuel-pump-related structural implosions. The same system failure reoccurred after the secondary repair. The service department manager later ordered a full system replacement from the manufacturer, but the manufacturer declined to cover the repair. The contact stated that Ford special service message: ssm 22277; stated that when severe fuel system contamination occurred on the 6. 4l platform, technicians could no longer attempt to clean or repair the original fuel tank and must replace the tank entirely to prevent recurring pump contamination. The failure mileage was 175,000.

Tank full of diesel fuel contaminated with water and some debris. Ford will not warranty but several parts of the fuel system developing rust. This vehicle is equipped with a fuel water separator as standard equipment. So Ford has equipped the truck with a fuel water separator but several of the parts in the fuel system are very subject to rust if there is any exposure to water. So as soon as the vehicle is exposed to water in the fuel there are parts that will fail and are not covered by warranty.
