FRONT ACE PIPES

I have a bad leak in one of the front ACE pipes (lower one I think). Trouble is there are 5 different pipes listed on line. Anyone know which is which? It's a D2 BTW.

Is there such a thing as a schematic or diagram for this?

You need to work out which pipe and also how it is damaged, is it a failed seal or a cracked flange on the pipe.

Follow the pipe and see where it goes AFAIR lower pump right side of block rams.

Rear pipes lower pipe goes to back of rear ram.

May be cheaper to convert to hoses.

I have already had the rear pipes done. As I have a back problem I am unable to do the work myself. I asked for identification of individual pipes so that I can save a day on fixing it by my local independent garage by getting the pipe myself which they don't mind. In the meantime I'm going to use the bypass pulley until I'm in the position to get it sorted. BTW I'm pretty sure it's the bottom pipe.
What does AFAIR mean?

Thanks, another one to add to my obviously lack of internet vocabulary.
