2008 F350 Ford truck, bad high pressure fuel pump. Ford refusing to support their warranty. Running rough, with no high end power. Stalled while trying to pull out into busy traffic. Slowed to 20mph in middle of highway traffic. Ford dealer analyzed trouble to high pressure fuel pump which should be covered by Ford 100,000 miles/5yr warranty. Ford will not support their warranty due to rust found in fuel tank. Rust in the system would be a failure of Ford filtering system / design which should be covered by warranty. Cost of repair is $8500.

3 times in the last 6 months my Ford F350 has shut down while I am driving, it locks me out so I can't even turn the engine over and I have to try to coast to a safe place out of traffic. All 3 times the fuel gauge reads over 50 miles to empty, the last time it read 140 miles to empty. The fuel lines are sucking in air, I get high and low pressure codes, I add more fuel(deisel) and then have to bleed all of the lines of air and prime the pumps. I have to do this on the side of the road or in a parking lot if I am fortunate enough to make it that far. I pulled the tank and pulled the fuel sending unit out, upon cleaning out the tank found a plunger rolling around. This plunger goes in the fuel sending unit, closing a valve that sucks fuel if the main suction gets clogged. It is about 2 inches higher than the main suction. Because the plunger has fallen out, this is where it is sucking fuel from, which causes it to suck air when there is in fact still fuel in the tank. I called Ford service and was told they replace these units all of the time, it is a manufacturers defect but not covered if your vehicle is out of the 36K warranty, when this most commonly happens. The last time this happened a friend pulled my truck into a parking lot, while he was pulling me in, there was another Ford truck being pulled in after running out of fuel while the gauge still read 50 miles to empty. This is very dangerous when it happens on the interstate, you have no power steering at this point and can not easily handle the vehicle due to the weight of this vehicle. My wife would never be able to handle the vehicle if this happens. I won't let her drive the truck due to this.
