injector lines

[hdm48]

Does anyone know for sure what the inside diameter of our injector lines is? I have heard 1. 8 to 2. 0 mm. But I think they are larger than that. Has anyone measured any?



Thanks

According to my cummins parts catolog the injector lines for the 89-90 non-intercooled trucks are 2. 0 mm and the 91-93 intercooled trucks are 1. 8mm



From what I can gather in 91 the injection pump pressure was increased and the delivery valves and injection lines were changed accordingly.

Now THAT makes me wonder. Are the delivery valves from a early 91 better for our later 91's or worse? I guess I need to do some more homework. Thanks for the reply.
