'99 Cummins N14 Redtop Extreme RPM Hesitation

So I have a 1999 Classic XL with a N14 Redtop that has 1,029,xxx miles on it and I was bobtailing home with it when it started to get some extreme hesitation/stutter when accelerating from a stop on the RPMs once I got it up to speed it didnt do to bad but I can also notice a stutter on the RPMS when parked and hear it a little bit. Truck allegedly had new injectors put in and it does have new fuel lines from the engine to the tanks.

Other thoughts Ive heard have been:

1. Fuel filter clogged or put on wrong and sucking air.
2. Air being sucked into the fuel line ( Truck does not lose prime when sitting and starts fine).
3. Injector going bad.
4. Clutch slipping?
5. Not getting enough air

Anyone else with a thought whether it be one of the above is appreciated and discussion welcomed. I havend looked at anything yet and waiting to get back home with my other truck to look at some stuff. Gotta keep the revenue flowing!

 

Definitely will. I forgot to also mention the Truck for as old as it is doesnt really seem to blow smoke like older trucks generally do. When I had it stitting parked at the house I had to rev it majorly up really high to even get a tiny bit of smoke from the stacks. Kinda had me thinking its not getting enough fuel

 

I planned to take it to a local dealer that does cummins and do a Injector cut out for one hour labor and what not seeing about taking a ride with the Computer hooked up. Im checking the fuel filter when I get back home Tuesday before I go do that though.

@062 it normally hessitates when Accelerating when trying to give it fuel. You hardly notice it if it happens at all at road speed bobtail but When accelerating from a stop light it throws a fit and thats when its worst. Also Im not sure about the Screen on the pump.
