I am new at diesels ( bought my fist 1983 300d yesterday ) and have my 1st question : there is several little hoses between the injectors , and some of these leak .The manual call them "leak hoses"( funny , isn't it ?) . What are their function ? If I am going eventually to run on WVO , should I replace with a different material ? And finally , can I just pull them out and replace them without risk of air entering the system ?
Thanks in advance,
