thofte Posted October 11, 2011 Share Posted October 11, 2011 (edited) What are the size of the vacuum-hoses going into the carburator (width)? 3mm or 4mm? On a stock leone 86' ea82. Edited October 11, 2011 by thofte Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted October 11, 2011 Share Posted October 11, 2011 (edited) Well... in inches, Those are 3/16" ... seems to be Equivalent to 4.76 mm; so I Suggest to Use 5 mm Vacuum hose. http://www.trueknowledge.com/q/convert_3/16_inches_to_mm Edited October 13, 2011 by Loyale 2.7 Turbo web link Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 11, 2011 Share Posted October 11, 2011 Typically Subaru uses 5mm and 6mm vacuum line. GD Quote Link to comment Share on other sites More sharing options...
thofte Posted October 12, 2011 Author Share Posted October 12, 2011 (edited) 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? Edited October 12, 2011 by thofte Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 13, 2011 Share Posted October 13, 2011 (edited) 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.
