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!
