Question about 2008 Ford F-350 Super Duty

1 Answer

Huffing after letting off gas / '08 Super Duty F350

When I let off the fuel (diesel) I get this sound almost like a huffing/grinding sound from the passenger side, near the firewall/ tranny hump. No loss of power, no fluctuations in the turbo, and it doesn't make the sound any other time except when coming off power - almost sounds like something winding down. Any ideas?

IF (big if) maintenance was performed properly, it should be great for again that much mileage.
You might want to have the Tranny and the oil pan contents check... just to be sure that all is well.
Anyway, it is a great engine to take a chance on... and 150 K is just broken in......

Check door rubber seal for damage / wear.

To test exhaust simply place a flexible object over exhaust pipe to seal it. If no leaks it should blow it off.

How do i change the fuel pump on a 2007 F350 super duty 6.0 diesel

siphon gas out drop the tank undo the harness twist the retaining ring pull pump. install in reverse.

probably be easier to just pull the truck bed off. usually requires unbolting 4-8 bolts holding bed on from inside the floor of bed. unhooking wiring harnwess and unhooking gas tank filler neck from hose leading to tank. you will need help of at least 3 others to pull the bed unless you devise a lift or a stand for your bed to sit on. think of it like a semi truck unhooking from a trailer. bed stays put truck moves forward. replace pump and back up under the bed and reattach. good luck

2006 f350 slowly lost power on the highway untill it comletely stalled and wouldnt start at all, I had to be towed.

Is this a gas motor or a diesel? Either way, there are a few things to check. If this doesn't help, reply or repost with more specifics. Either type of engine will do that if there is water in the fuel. Was it damp/rainy recently nad the tank less than half full? Did you just get fuel? Even if not, drygas or diesel fuel conditioner won't hurt. If it's a gas motor and you just got fuel, is it possible that diesel got put in the tank? I've seen it several times (once because a valve failed at the gas station) I figured it out by taking a gas sample and smelling it. If you let the sample sit for a while, the gas starts to evaporate and the diesel smell becomes more prominent.

When you get some fuel you can unscrew the fuel filter and fill it with diesel. Then put the filter back on without spilling the fuel.

There should be enough diesel to prime the motor and get rid of the airlock. Also with diesels make sure you are using the correct tank if you have a tank switch.

Many possibilities:
Is it a Diesel?
Camshaft position sensor recall may cover it.
Gas or Diesel:
Fuel Pump and/or relay.
Fuel Filter.

Engine codes could help if Check Engine Light is on.
