Simple question


Recommended Posts

Silly me... bought 4m of 3mm and 4mm.. was only 20 bucks, doesnt matter.

-

EDIT.

 

But are we talking about the same thing here? I am talking about inside width here. 5-6 mm is 0,5 and 0,6 cm which would be huge comparing to what i remember. Wouldnt that kind of inside width make it loose pressure?

Yes I am talking about ID...... I don't know what you mean by "lose pressure" as these are vacuum lines not pressure lines.... Please clarify.

 

I have not seen anything smaller than 5mm in a Subaru unless you are talking about the vacuum lines behind the dash for the HVAC flappers, etc

 

Subaru used vacuum lines mostly smaller than 1/4" - which is just over 6mm. 5mm works very well. I buy bulk 5mm silicone vacuum line and I have some 6mm on hand as well. I've never used or needed 3 or 4.

 

I find this to true of most Japanese cars. I recently did an engine swap in a 300ZX and we redid all the vacuum lines with 5mm and a small amount of 6mm. Again - no 3 or 4.
