Hi everyone, I have a KH 191 Kubota excavator with an S 2800 engine. The injection pump has a plate that the lines going to the injectors hook to. Coming out of the plate is something these lines hook to. These somethings appear to screw into this plate and I have a leak between these somethings and the plate. It appears after looking on line to be part of the injection system so I do not want to just start tearing things apart before I know what they are and what they do and what I can break. I know this is not much to go on but I can not post pictures so any help you can give me is much appreciated. Thank you for your time Neil
