im gathering parts and am planning on building a 6.7 long block for next years pull truck a early 04. was looking over the fuel rails on the 2 engines tonight and debate trying to use the 6.7 rail for size reasons mostly,but id have to adapt the 5.9 sensors to it, are the 6.7 injectors and rails good for more rail pressure than the 5.9?? don has said the 6.7 injector bodys wont work with the 5.9 ecm. anyone have any info on these comparisions??
