vacuum hose size?

Replacing my BOV's, so also replacing vacuum hoses as well. What size should i be getitng? Seen that they sell from 3mm-18mm but i have no clue which size i need.

cheers.

 

6mm

 

Thanks

thread hijack as i was thinking of doing the same, how many metres of it would I need for a TT?

 

A billion meters.

 

Or possibly about 2 or 3 meters. It's a few bucks a meter, so go nuts, always handy to have around.

If you doing ALL the vac hoses, grab some 8mm as well as some 4mm.

There's a few random bits that use both 4 and 8mm, majority is 6.

 

4mm vacuum hose
6mm for actuator lines
about 3 metres should cover it.

 

Nah not replacing all of them, my BOV's atm are in the engine bay connected to the intake pipes, so replaced them with regular ones so i can put em somewhere near my POD filter. Just needed the vacuum hoses relating to the BOV's for moving them lower.

Ordered 5m of 6mm anyway, so lets hope that does the trick.
