I'm considering swapping out all my black vacuum hoses for colored silicone hoses. There are a couple hose kits out there. One has 3mm, 4mm and 8mm ID hoses. Another has 4mm, 6mm, 8mm, and 12mm ID hoses.

Anyone know what size vacuum hoses the GK actually uses, and an approximate length needed of each?

And, bonus question, same query about swapping out black split loom in the cable harnesses for colored split loom.
