V12 Facelift Vacuum hoses sizes and length
Hi everyone, planning to replace all vacuum hoses on my facelift 5.3, tried to search for existing forum threads, but information is quite different there.
can anyone please tell what are the sizes for vacuum lines and approximate length if possible. I have seen on some forums that there were kits on ebay, but not any longer.
Thanks

You need 4mm ID vac tube. It is best to buy a length of silicone vac tube and cut to the lengths you need. Best UK supplier is Viper Performance Hoses:

Are you sure its only 4mm ID hoses everywhere? i have noticed that some are thicker.

I think the only thicker one is the one from the A bank throttle spigot underneath A bank throttle bosy, to the cruise control bellows. For this injection hose will do nicely in the correct ID. Do not forget, if you have the GM 400 three speed gearbox, to renew the vac tube from the gearbox moderator to the inlet manifold, end of A bank spigot. This makes a HUGE improvement to the responsiveness of the box.
