Im needing to know the cylinder locations on an 08 6.4. I have to replace the #7 injector.

 

Left bank 2,4,6,8
Right bank 1,3,5,7

 

That's correct if you're standing behind the motor. When you open the hood and are looking at the motor the bank on your left is 1,3,5,7....

Just note the direction of the arrow in the picture provided is the FRONT of the engine.

 

Should have mentioned that thanks

 

Bank 1 pass side Bank 2 drivers side.
