I only put the catch can last on the list because of importance really. I really doesn't matter when you do the catch can. I couldn't agree more about the dawes and needle valve, but you need to do the dawes before you do the needle valve. I'll edit my post to make it more understandable. If fitting both, install the two together and set the dawes before the needle valve.
The glow plug timer is something that does need to be done too. Something I need to do to my Patrol. Not to forget installing metallic tipped glow plugs too.
