Hi my name is***** will be glad to help. There is air in the system from changing the fuel filters. What is the Cummins engine model number from your engine tag so I can give you the proper bleed procedure
You will need to prime the fuel system to get the air out of the filters and the fuel lines
With your filters full of fuel and bled of air from the primer pump crack the injector lines loose while cranking over until it starts to want to run and you get fuel from the lines and then tighten the lines and start. Make sure there are no leaks at the filters. Let me know
Thanks for the info. Same. Pump primer pump with bleed screw or line cracked loose on filter housing until you get fresh fuel and filters are full of fuel no air, tighten, then pump[ until the resistance from the pressure is felt and try starting. Crack the injection lines if unsuccessful while cranking. Once running keep at 1200-1500 until it smooths out then let idle
Hi, Did you get this resolved or still need help?
