Help identifying pipes please

Hi, I recently bought a 2004 disco 2, td5. It has lots wrong but i need help identifying a couple of pipes please. Have the haynes manual but can't find it for looking.
#A seems to be missing a pipe on vacuum stud if that's what it is
B pipe was melted on to exhaust seems to have a small amount of transmission fluid coming out of it. It terminates the other end passenger side on top of the transmission. But where should the melted end go?
C pipe looks like it comes out of the diff or transmission also but on drivers side. It has a bend on the ther end and has come out of somewhere but can't find where. The bend is the wrong way to come from #A it would have to do another 180 degree bend. Cheers Lee. ( its an imported uk landy now in nz)

C-pipe looks like a typical axle breather pipe, so is ok as is ...

A grown up will be around soon to assist with the rest, as I only got up to raid the fridge ...

'A' looks like the fuel pressure regulator and the spout is where diesel will drip from when it isn't working 100%.

I left click on the relevant pic then right click on the bit I want to 'open in a new window'. Click on the blue number by the part you want & you'll get a menu with part numbers.
