Boost sensor hose diameter??

Hello,
Who can tell me the int diameter of the boost sensor hose?
I need to change mine but my car is in my parent's home and I forgot to take its dimension
Thanks

That sucker is small, say 3/16 or 1/8. Don't know what it would be in mm. You could probably use some Tygon tubing, it works good in a pinch. Get that at a lawn mower shop.

Yes, this hose is very small and I think the diameter is 3mm
1/8" in mm is 3.175mm
Thanks for your confirmation

I will change it because my idle is sometimes good and sometimes not
I will try to post a picture

So if a poor hose or a silly aftermarket length will give a poor idle / poor boost ?

Well, we're talking about a small hose going to the boost transducer. It should not have much affect if it is a silly aftermarket length. If it comes loose it may have an effect on idle.

I'm sorry for posting on an old thread but I'm trying to figure out where this hose goes to.

On the turbo engine, this little hose normally comes from a tee fitting about mid point on the firewall and goes to a small black box under the wiper motor area.
