Hi all and anyone in the future who references this.
So the parts actually arrived on Saturday which was a massive bonus seeing as I selected standard delivery and I fitted them yesterday.
I just want to say "WOW" and a big thank you to this thread and all contributors! I replaced the fuel trap and 3 of the 4 vacuum pipes (I couldn't unplug the small one from the behind the throttle body which leads to the fuel trap a few inches away) and I blew through it and it was fine so happy days.
I cannot believe how such an unsuspecting set of plastic, thin, tiny pipes can turn my dream machine into a nightmare if broken!! I took some pictures for others to reference if they ever get the same problem! Seriously overjoyed and shocked! The car felt completely broken and now drives like a dream!!
It's rare to find a forum and a thread where the answer to a problem/fault is so conclusive when the fault appears to be so dramatic and I'm happy and thankful to verify this through my own personal experience, I hope this helps others in the future.

Underside of the air filter box with old pipes in the shot (Red pipe missing elbow which was problem #1). The yellow pipe loops round from that bottom nipple to the air temperature control valve (see pic 5). The red pipe goes onto that second nipple above the yellow one and goes round the back of the throttle body behind the throttle stop. (See pic 5 for a rough idea, as stated before on this thread, its inaccessible to take a picture of.)

This is the longest vacuum pipe coming from the underside of the ECU which leads to the fuel trap.

This is where the pipe above leads to and as you should be able to see here, mine has actually snapped (problem #2). The other pipe attached to the fuel trap is the short pipe that also leads to the rear of the throttle body and is the only one I didn't replace but I pulled it from the rear elbow and blew through it, slid it back into the rear elbow and luckily it was fine so I just attached it to the new fuel trap.

If you couldn't see the elbow breakage of the longest pipe in the previous picture then that one should clear things up.

Finally, the air filter box is screwed back into place with the red and yellow pipes proudly on show. ("Proudly" because I'm an amateur DIY'er!)
In retrospect, I only 'needed' to fit a new elbow to the fuel trap long pipe (ECU pipe) and a new elbow on the red pipe which was missing because I blew through every pipe and the fuel trap and all were very clear. However, given how insistent FlyingScot and Brivinci was on all of them being service items
the best and reassuring thing to do is just replace them all if not just for peace of mind.
Once again, thanks all and I hope this helps in the future! Problem RESOLVED!!!
