Looks sweet, I like the line work on the fuel system & the rest.
Do have a tip for ya if you haven't changed it already.
On the lines going behind the thermostat housing that you put pieces of hose around, ya might look at using
rubber coated line clamps to keep them steady. Those ones aren't the best, just some heat shrink on a line clamp. The nicer ones that are pretty much like what we use in aircraft plumbing are
Adel, neoprene cusioned line clamps . Now THOSE are the poo, I use them on any hardline project.
You can bolt a couple together to keep lines from rubbing (beats zip ties!), and/or use a bracket to affix long lines in place to prevent vibration.
