Vacuum hose to fuel regualtor

[BOOST LEAK]

hi all, the fuel regualtor vacuum pipe has fared and spilt on my S3, does any one know the correct size in mm I need ? Is it 3mm/3.5mm/4mm ? I've tryed 2 measure it but can not be sure, I've seen some silicone pipe on eBay but id like to buy the right size. Thank all.
