What are the size of the vacuum-hoses going into the carburator (width)?

3mm or 4mm? On a stock leone 86' ea82.

Well... in inches, Those are 3/16" ... seems to be Equivalent to 4.76 mm; so I Suggest to Use 5 mm Vacuum hose.

Typically Subaru uses 5mm and 6mm vacuum line.

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.
