on my saff 4x4 was thinking of getting some new hoses as mine are original and a little perished.

I'm gonna be getting a full set care of roosemotorsport i think, i'm just wondering what the ancillary hoses are (9 of them)

I know the coolant hoses run from the radiator to the engine, but where are the ancillaries, are they hard to fit, and should i replace them?

i was thinking of black, as the car is black but i'm open to other suggestions, gonna do the rocker cover black at the same time too
