Three problems related to diesel fuel system have been reported for the 2008 Ford F-450. The most recently reported issues are listed below.
2008 Ford f450. Consumer writes in regards to a safety concern of an auxiliary fuel tank the consumer stated he purchased the fuel tank and it was installed on June 1, 2011. The tank was made of the same material as tool boxes for truck beds. Recently, a single bolt attached on the passenger side became loose and slipped an inch and a half out of the hole securing the tank to the bed of the truck. The bolt threads were stripped up to the end of the bolt. The nut was at the end of the threads of the bolt. The bolt was protruding outward in the bed of the truck and was bent at a 45 degrees. With the bolt bent over, the tank slid an inch forward in the bed of the truck. The driver side bolt had also loosened, but was still secure with a nut. The establishment where the consumer made the purchase, informed him he tank was supposed to be movable. They stated it was supposed to be secured with one bolt on each end.
The coating on the interior of Ford diesel fuel tanks corrodes and collects as sediment in the fuel system. The sediment, collects at the botton of the fuel tank and is sucked into the fuel system. In this incident, the failure began with the check engine light illuminating. The dealer, replaced the sensor, then at a second time the fuel element, and finally the entire fuel system required replacement. The fuel lines become fouled, the fuel pumps become clogged and require replacement. As the coating continues to deteriorate, the only recourse it to change the fuel tank, the sensors, and entire fuel delivery system. We have had 3 Ford vehicles f series experience this problem. In this case in less than 18 months from date of purchase, the fuel elements and sensors required replacement we are reporting this as it seems to be a defect in all the Ford diesel fuel systems. As the fuel systems become clogged, the vehicles lose power without warning and create a safety issue and driving hazard not only to the vehicle operator but other motorists.
I own a 2008 Ford F-450 with a 6. 4 diesel motor. I have numerous issues with drive train problems since I took delivery. Finally, while driving on a 4-lane highway doing 50mhp the motor quit running. Bake and steering failure followed. After getting towed to a dealer and after 3 days to find the problem, I was told there was a burnt wiring harness inside the high pressure fuel pump system. I asked if this was a single issue or wide-spread. I was told that there is a TSB (tech service information) regarding this failure. I asked why no recall and was told this is not a safety issue. I consider my truck to stop running at any speed to be a safety issue. The repair took 11 days to complete. In order to make the repair the cab and the front body have to be removed from the chassis. I can see why Ford would not want to replace these defective pieces on all the 6. 4 diesel motors, however by waiting for each one to break down, and possibly causing a serious accident is a terrible business decision. Please help other owners!!.
