I have never changed my fuel filters myself on my ISC 350. I always have it done at either Speedco or other truck service centers. All of them have pre-filled the fuel filters with CLEAN diesel fuel.
Cummins states to use the lift pump to fill the fuel filters however when doing that you should only change ONE filter at a time, NOT BOTH. Then once the filter has been fully filled you can start the engine and let it run. Then change the other filter and again use the lift pump to fully fill the filter before starting the engine one more time.
When pre-filling the filters you can immediately start the engine without any difficulty.
It just depends on which procedure you are willing to follow.
BTW, I recently ran my engine out of fuel
but was lucky enough to coast into a fueling station right at a diesel pump
. However once the tank was full (I pumped 110 gallons) it took me several attempts using the lift pump to remove ALL of the air pockets before the engine would not shut off after getting it started once again. My diesel tank holds 128 gallons so there are 18 gallons of diesel in the tank that are not usable.
