I drove 5 miles and not dies i have to check code for fuel injector but i think is ok Wow thanks guys

 

Took me forever to figure out how to post pictures here too. I open my gallery in another window or tab and go to the picture I want to post in the thread. Then you'll either have to hit the post reply button, or if you just start typing in the little window below the last comment, you'll have to hit the "go advanced" button so you have all the little symbols above and the smiley faces on the right.

Then go back to the window with your gallery in it and right click the picture and select "copy image location". Then come back to the thread where you're typing and click on the little button. A little window will pop up. If you right click the box in that pop up window and select "paste", it will put your picture info in the box. Then just hit ok.

I borrowed this from your gallery.


Thanks for taking the photos. I hope you don't mind me showing those to others in the future to help explain what they're looking for.

[/IMG] where i can hit ok

 

 

If you hit the little you should have a window that pops up like this.

 

I had the screens very badly clogged with varnish like stuff. It seems to accumulate from the inside and I was able to easy blow it off from the outside.
The bottom screen was perfectly clean.
Would that conclude that the dirt is coming from the engine?

 

Those are from the pick up that is gunk that is in your tank.

 

No, I'll agree it's coming from the tank. There's a check ball in the fuel pump that keeps the fluid from going backwards through the pump into the tank. Have you thought about doing the in tank mods to keep this issue from coming back?

Glad to see you got this figured out.

 

So how come the main screen is perfectly clean, while the varnish is on the inside of those cylindrical filters?
I was thinking about those mods, but my truck didn't have any issue with air in the fuel for the last 203,000 miles so I don't expect it will start now
My flatbed has a steel tank, so don't think harpooning is necessary, especially that having 30 gallons of diesel in the tank I couldn't really see it. Nice to have dump bed, that will allow the access to the top of the tank without dropping it.
I hope the dirt was the problem. Didn't have a chance to drive the truck after cleaning and the problem shows after longer drive.

 

Does one screen have a finer mesh than the other? Was there a period of time that a tank of fuel sat in there for an extended period and allowed things to settle, grow on that screen?

The dump bed does make it nice. Keep an eye on the steel tank. Some had issues with the inner coating delaminating and temporarily clogging the pick up foot. It's easier to spot that problem since you'll see large pieces of the coating floating around in the tank.

 

Sure the cylindrical filters have much smaller holes than the main screen, but again it wasn't the mechanical dirt that clogged them, but some fuel deposits. I had the issues on small gasoline engines, when fuel left for the winter dried out and left clogging residues, but this is the first time I see it on diesel.
Who knows what is the whole purpose of mixer? Don't recall seeing it on any other engine?

 

Main problem solved, althought once at starting at green light the engine stalled for 2 seconds. Hope it was just reminding air in the system.
Turns out I bough the truck 3 years ago with tank filters already partly clogged. Now my boost goes to 18 psi, when before max was 16, engine starts faster and I don't hear the loud pump noise on morning priming anymore.
So when you hear the pump noise and the engine take extra second to fire up, better check your tank filters at convenient time.
Thanks for the forum help.
