Vacuum Hosing

[Craig]

Hey all,

Was wanting to buy some Vacuum Hosing of eBay to make the engine look a little bit prettier. My question to you is, what diameter do I need for Engine Coolant and the hoses to the dump valve etc? 3mm & 5mm seem the most commonly listed.

Bump for the morning folks!

Off the top of my head it's mostly 4mm with some 6mm piping around the place but I've never checked. Wait for someone more image-conscious to confirm!

3mm and 5mm, the coolant is 8mm
