Thanks!
Should just be airbox out to get a good view of what is going on. The feed from the engine to the distro block is not easy to inspect or replace, saving this one for a rainy day.
I just used Aeroflow product, worked with it before and it is reasonably affordable in terms of AN fittings, I just copied the whitbread ones from their photos.
I didn't actually do the top turbo line back to the block, it came like that when I bought it, would probably route it slightly different when I redo it at some point.
These are the parts I used for the distro block to lower turbo (LP) feed line:
2x AF202-03, 1x AF200-03-1M, 1x AF359-03, 1x AF351-03, 1x AF91-1909 (heat sleeve, optional extra but nice to have) and some crush washers from mitre10.
