Silicone Vacuum Hose

[DanThMan1983]

Gonna order some black silicone vacuum hose. My question is, whats standard size that fits about anything on our cars with vacuum/boost? Sizes range from 3mm-19mm in diameter. Thanks guys. I would measure myself or guess but the car is not here and neither are my measuring tools. I figured some one on here would know. Thanks again,
Dan

Just went outside to measure they are 3/8's on my car calculate 3/8in X 25.4mm/inch and that will give you the size in mm's Okay, they are 9.925mm.

Did you measure the inside diameter? That's how they are sized, not the OD.

RRE's Larson Silicone Hose Kit

This kit includes 4, 6, 8, and 10mm hose. I'd guess that you'd need some of each.

4mm is most of the smaller stuff.
