Hi there, does anyone know the different sizes of o-rings needed to refresh the vacuum lines without having to replace the actual hoses, that would get unnecessarily expensive as what starts failing are just the o-rings. I need particular help with the crank vent hoses and the one that connects to the break booster vacuum line. in my case, my car has a CSL airbox and I am getting DTCs that makes me verify for sealing. so I want to actually renew the o-rings.
