Thanks in advance. I know there are many threads on this topic but none seemed to give me what I needed. I changed the fuel filter on my 1982 k5 chevy blazer, 6.2L diesel. Air got introduced to the system and now it won't start. Realize I need to bleed it but can't figure out what this actually means. Attached are some pics. On another thread I saw the statement, "you gotta bleed the lines at the injectors.... with the starter. crack'em all loose a turn or 2 then crank until at least a few or all start weeping fuel then retighten." I'm new to diesel so I'm not really sure what, in the pictures, needs to be loosened... or where they are. Please help!
