I'm going to be swapping in a rebuilt set of injectors on Wednesday. Upon looking at the diagram for the fuel lines and fuel rails, it was brought to my attention that I may be able to leave the fuel lines attached to the fuel rails and remove it all as one piece. Can I do this?

 

After looking at the FSM, it looks feasible.....

 

No , i think you have to remove the lines on the ends of the rails.I just did the headgaskets on my 3.0 and tried to disconnect as little as possible.But i did have to remove the end lines for access to some bolts . Also the injectors go in at a slight angle so trying to remove six injectors at once,you could cause some damage.

 

I too had to remove the end lines from the rails when I did my injectors.
