Spent more time making up the remaining oil lines and installing the last couple of fittings. Once each line was final fitted I stuffed a small ball of cotton cloth into the end of the tube and blew it through with compressed air then repeated from the opposite end then a final blow out with just air alone.
All the lines have been fabricated but I still need to replace a couple that were made with the bad flaring tool which I'm afraid could leak due to the uneven flair. Easier to redo them now than after everything has oil in it.
