Truck runs like S@#$

1999 cummins n14. Last trip is was random misfire then when i came to a stop it acted like it ran out of fuel and died. Took fuel filter off and it was little over half full. Started back up and seemed fine then 5 miles down road another traffic jam and it did it again. Fuel filter was almost empty this time. Got it home replaced every line on truck including check valve. 2 months ago i got a new fuel pump. Had injector cutout done and they told me 6 and 3 were weak. I changed 6 but didnt do 3. I cant imagine a weak injector causing the fuel filter to go empty. Highway heavey told me i could send pump back in and they would check it but i would need to buy one just incase it isnt the issue. What would cause the filter to run empty besides air or a bad pump?? Also looking for a machanic in KY that knows these engines.

 

Checked valve and its fine. Had pickup tubes out of tank and those were fine also

 

When the truck idles is diesels pretty bad also. Been told it could be bad fuel but this has been going on with the bad adle for awhile and plenty of fuel through it.

 

Not sure what you mean about fuel slobber, but it misses and stumble at idle then at 1000 higher you can hear it miss randomly still. I havnt drove it after i replaced all the lines but can tell its still jacked.
