Attention: TDR Forum Junkies 
"if you have the Cummins part number I will look it up". I thought that was his job?
GLASMITHS, that is his job!!!! There is no excuse for that kind of attitude, a nice letter to the branch manager should be on your list of things to do, if you are so inclined.
The tubes are a compresion fit between the fuel line nut and the injector. The threads for the nut are in the cylinder head once the nut is loose you can usually pry the connector tube out gently with a couple small screwdrivers. Hint; if the nuts are so tight that you have a hard time breaking them loose, smack the wrench flat with a hammer and flat faced punch, this will loosen them up. A Johnson
