Can anyone tell me what these are?

Evening all. I'm finishing a project someone else started so not having taken it apart I don't always know where bits go
Its a 110 V8 and has a 3.9 injection engine from a Disco fitted but not connected.
I've worked out most things but am stuck on the attached.
The one ringed in red I know is the brake booster vac hose.
The one in blue is that the vacuum to the fuel regulator? Runs a long way but I can't see it goes anywhere else.
Stumped with the green outlets in the water hoses, what are they for? They look like they've been added, any idea why the previous owner would have done that?
Assistance greatly appreciated!
Also does anyone know what the fitting type/size is for the fuel inlet on the fuel rail? I can't find a part for it so presume the pipe and hose were one item. I'm trying to find a connector. Pic attached for that too.

The Green ones are probably for a LPG conversion and not standard

in the heater pipework, possibly for an engine preheater like the Kenlowe Hotstart??

Good call! I bet that's it, the gas condenser probably was connected to the water circulation to improve its change from liquid to gas. Well done.

Without heat, LPG will freeze up a reducer very quickly. They're also more efficient when hot

Our “mud ball” runs LPG from cold start, is the UKs LPG scared of the cold.

But yes probably for the wimpy UK LPG system.

Anyone know if the blue one is the vacuum for the fuel regulator or something else?

Also any ideas on the fitting type/size for the fuel rail?
