Total loss of power

[9secondlx]

Got a 550 in this week for loss of power on the highway, 88,000 miles, changed fuel filter replace 2 injectors and resealed the other 6, drove it for @ 30 miles and died on the side of the highway, waited a few minutes started backup and drove onother 2-3 miles and would'nt get out of its own way. Got back to the shop and pulled the fuel filter again and was full of silver flakes, fuel tank lining? My question is why didnt it clear up after changing the fuel filter. I need to check fuel pressure, thinking the screen in the tank is getting clogged? or bad fuel pump?

Those silver flakes are indeed indicative of your fuel tank lining. You're going to have to drop the tank, clean it up really good, clean the fuel pickup, as well as the screens in the mixer. Which truck are you working on? You've posted in the 99-03 7.3L section, but your signature doesn't correlate. If it is the 6.0, then I have no idea if your fuel pickup has screens or not.

O not the same truck this is a 01 7.3

You might want to search for Hutch modification as long as you've got your tank off. Here is Guzzle's take on it:

K here is what i found today, replace fuel pump, tank, and cleaned lines, here are some pics
This came out of the fuel tank side of the pump


This is a couple pics I took of the inside of the tank with my borescope.



This is a video I took with my bore scope of the inside of the tank.


Final result: Fuel pressure before fix, 38-56 pulsing up and down, after fix 60-62 steady, Runs like a brand new truck!!!

Congrats on getting it fixed so fast. Were the screens in the mixer clogged?

Not sure what you mean, may have missed something, where are they located. Thanks

I dont do much diesel stuff, but good at diagnosing problems, not afraid to jump right in there. This one was kicking my butt this time. If this didnt fix it I was thinking maybe bad cat, but worked out.

They are in the fuel pickup assembly - I know a lot of people hate this guy, but his videos are informative. Watch this one and it shows where the screens are:

Bad cat? Catalytic converter? I don't think yours should have one. My 2003 doesn't - never did. If you have one, I'd let it "fall off" as the diesel soot has surely clogged it by now.
