Fuel System problem '04, F250

[artmedina]

Yesterday my truck gave me the type of symtoms that I had previously observed on a gasoline powered vehicle when the fuel filter is dirty. A complete loss of power before shutting itself off. It did shake and the injectors were knocking before the truck died on me. I let it stand for a few minutes and it started just fine but no power to go forward. It would only go forward about 5 miles per hour. I checked the A/T Fluid level and that was full. I'm hoping that by draining the water/fuel separator I can correct the problem; although, I did not see the WIF light come on.

Today, I turned the truck on and drove it home, about one mile; the injectors were making a big racket. When I slowed down like at intersections and for stop signs, the truck almost shut it self off and I had to step on the accelerator and the brake at the same time in order to maintain the RPM a little higher.

I would like to get some tips and pointers as to what to attack first. Additionally can someone link me to a picture of the location of the fuel filter and the water/fuel separator?

Thanks,

Art

I don't have a picture, but inside of the drivers frame rail, about middle of the driver door, make sure your not laying right underneath it when you change the filter. The other one, if you are staring into your engine bay standing in front of your truck, it's about 1 oclock right passed the fan shroud about the same shape as your oil filter just alot smaller, has a black cap, pull it off the filters right there. The one inside the frame rails a little messy, but still pretty easy. should take about 15 minutes or so for both altogether.

Thanks Hoss,

That was a lot of help; I have changed both fuel filters.

I'm still having a problem with the fuel system; I started the truck and it ran for about two minutes then it began to make a racket with the injectors and the engine stopped. Now the truck cranks but it won't start.

you need to check the fuel pressure spec is 45 to 55 psi under load

Thanks for your helpful tips Hoss.

It turns out my fuel pump had gone out on me; after a few hundred dollars, I'm back on the road again.
