    Hi,

    I have an S3 APY & I took my TB off at the weekend for a clean and noticed the little hose connected to the top (not the main large hose) looks very perished underneath so thinking of replacing it but I can't find any info on it through search. Can anyone help?

    It looks like a vac hose but is connected to a metal hose further up with a check valve and doesn't look like I can just replace it with some silicone like the other hoses I've done. Does anyone know if I should bother replacing it if perished and if so is there something aftermarket I can use like normal extruded silicone etc..or a part number or proper name?

    Thanks!

    Its a vac pipe for the EVAP system... you can replace the rubber bit with silicon... the crimped cap needs to be carefully cut off then you can pull the hose off... its a normal pipe underneath...

    Will be the same as the OD of the metal tube... I think I have used 6mm in the past IIRC
