My LCF dump truck began idling a bit irradically. Driving the truck at about 40 MPH it began to sputter and lose power, until the engine turned off completely leaving me stranded on the road. I opened up the primary fuel filter and found it to be caked with a silver metallic material. I put in a new filter and was able to get the truck home, but the engine was not running as it should. I researched the issue online and found a lot of diesel Ford truck owners were experiencing the same problem, and it was because the fuel tanks were delaminating and getting sucked through the fuel system.
Our company has a 2006 Ford LCF medium duty truck with 30,000 miles on it and the 4.6 l v-6 powerstroke diesel. At about 24,000 miles we began having power loss issues with it. We pulled the fuel filters and found them clogged with what appeared to be flakes of silver paint. Assuming we had gotten a bad tank of fuel, we replaced them and assumed the problem would go away. Since then we have had to replace the filters 3 more times ( at $85.00 each time ) in 6,000 miles. The truck will start to lose power quickly, with no warning and can even stall suddenly. After researching on line, I have found that the problem is extremely widespread with Ford diesel medium duty trucks and is caused by the fuel tanks delaminating. The repairs can be anywhere from $600 - $8,000 depending on how much damage is done. …

2006 Ford LCF 450. Consumer states problem with fuel system the consumer stated he has been experiencing problems with the vehicle, since the day of purchase. The engine was replaced at 96,018 miles. The vehicle stalled and would not restart. The dealer changed the new ficm that came with the new engine because it was not done when the engine was first replaced. The dealer then found the number 2 and 6 fuel injectors had failed. The next day the vehicle was still running poorly with bucking and very little power so the vehicle was taken back to the dealer. They then found that the fuel pump failed so they replaced it. They also found the number 1, 3,4 and 5 fuel injectors had failed and replaced them. The dealer did not lower the fuel tank for inspection nor did they flush the lines per procedure. Several weeks later, the vehicle stalled again without warning. …
The contact stated that after parking the vehicle, it failed to restart. The contact attempted to "jump start" the vehicle; however, it would not start. I had taken the truck to an authorized dealer for repairs. They state that the vehicle is not under the warranty so I have to pay for it. Just for the diagnostic they were charging 575.00 so I decided to take to an other mechanic shop I am really disappointed with this Ford dealer. I paid a lot of money for this truck it has only 32 thousand mileages.. I found similar problems with other trucks same model same year. I still have my truck in the mechanic they replace the starter and the alternator. But the fuel problems still there. I call the Ford motor company they told me that I have to take to an authorized Ford dealer for diagnostic. So they can help me from there. I am going to take there to see what happen.
