Thank you and everyone who has provided information. I will be careful as I dont want to damage the connectors or the lines as I haven't been able to verify what the part numbers of those hoses to be able to replace them. I hope that i don't have to remove the def pump, doser, tank, etc to get at everything. I don't have a shop, just laying on a section of cardboard on my back in my gravel driveway. Part supposed to deliver Tuesday and looks like it will be a July 4th project.
