What is the firing order in 8 cylinder cummins engines?

There isn't a single firing order for all 8-cylinder Cummins engines. The firing order depends on the specific engine model and its configuration (e.g., inline, V-configuration). Cummins produces a wide variety of engines.

To find the correct firing order, you must consult the engine's specific documentation. This information is typically found in:

* The engine's service manual: This is the most reliable source.

* An identification plate on the engine: This plate often provides a model number which can be used to look up the specifications online.

* Cummins' online resources: Cummins' website may have searchable databases for engine specifications.

Without knowing the exact Cummins engine model, it's impossible to give you the firing order.
