TMeitz Posted June 2, 2002 Report Share Posted June 2, 2002 I know this has been posted before. I'm wanting to replace all the small vaccum hose and the size is???? 3.2 or 3.5 mm and about 45 feet. Might post this in the favorite board, TMeitz ??? Link to comment Share on other sites More sharing options...
pumpedTSI Posted June 3, 2002 Report Share Posted June 3, 2002 3.2................ Link to comment Share on other sites More sharing options...
TMeitz Posted July 8, 2002 Author Report Share Posted July 8, 2002 PumpTSI , You are correct. I went to order 45ft of 3.2mm vac. hose from Hosetechniques and the owner Luckey talk me into 3.5mm hose saying nobody uses 3.2 hose . So when the 3.5 hose arrive along with samples of all the vac hose that they sale. Only the 3.2 sample fit properly. I call him up and he was surprise that the 3.2 fit and the 3.5 fit very loosely. Luckey said he would put a hose kit together for our cars in the near future. And that now he knows about the 3.2mm situation with our cars. Thanks again Pump for the sound advise. TMeitz P.S. I was able to return the hose for a full refund. I should be getting my 3.2 hose Tuesday. Link to comment Share on other sites More sharing options...
my89Tsi Posted July 8, 2002 Report Share Posted July 8, 2002 Just ordered mine on Fri (net) called to change the order to 3.2, order was to going out today!they pulled it and made the changefor me.Guys running the 3.5 are having to strap the hoses on after running them for a while, then I was thinking that 3.2 might be the way to go.

indy_85stariones Posted September 7, 2002 Report Share Posted September 7, 2002 Am I the only one happy with 3.5mm hose from hose techniques? I have their sample package from this summer. The walls of their 3.5mm hose is much thicker than their 3.2 mm (and 4.0mm as well). I guess that one should get their sample package first -- then decide for yourself.

TMeitz Posted September 18, 2002 Author Report Share Posted September 18, 2002 When I tried the 3.5 hose it slid on so loosely that it had no grip to it. And I was having trouble keeping vac hoses on - on some ports. Under boost. With the 3.2 hose, it fits snug and have had no problems. Yes the walls on the 3.5 hoses are slightly thicker, but see no affects that would be a neg. with the 3.2 hose. TMeitz Link to comment Share on other sites More sharing options...
Rayman4449 Posted September 21, 2002 Report Share Posted September 21, 2002 I just ordered 3.5 from Hose Tech after I test fitted the 3.5 from their test kit on the car and it seemed to fit pretty good. I actually didn't think I wanted it any tighter. I will see but, based on the test fittings, I think 3.5 will do fine. And I really like the thicker side walls. ;D Raymond Link to comment Share on other sites More sharing options...
itimport2nr Posted October 14, 2002 Report Share Posted October 14, 2002 I'll be meeting with Hose Techniques tomorrow and they will be using the project 87 Starion ESI-R to put together a complete kit for our rides. Speaking with Lucky (owner of Hose Tech), we were at a conflict as to what the proper ID for the lines should be. He actually said that 3.2 is a weird size, with 3.5 being more appropriate.

Droben Posted October 15, 2002 Report Share Posted October 15, 2002 Where is everyone getting their hose from? Websites or local stores? Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2002 Report Share Posted October 15, 2002 I got mine from http://www.hosetechniques.com/. There has been quite a bit of discussion about the correct hose size. I ordered a sample pack from them that has all the different sizes an colors and went with the 3.5mm. After the test fits and final install, I think 3.5 is the way to go but I think 3.2 will work ok. I would order a sample pack for yourself and make your own decision. Good luck! Raymond Link to comment Share on other sites More sharing options...
88 MPI Posted October 17, 2002 Report Share Posted October 17, 2002 I got the 3.5 mm and they fit good for me. I didn't have any problems at all. ;D ;D ;D ;D ;D ;D Link to comment Share on other sites More sharing options...
importwarrior Posted October 17, 2002 Report Share Posted October 17, 2002 doesnt hosetechniques come with tywraps for all there hoses? i would tywrap all my hoses just to be safe! Link to comment Share on other sites More sharing options...
Rayman4449 Posted October 17, 2002 Report Share Posted October 17, 2002 I didn't get any tie-wraps with my order, although my 3.5 fit so tight that I wouldn't want to, but not a bad suggestion if someone is having problems. Raymond Link to comment Share on other sites More sharing options...

creed Posted March 23, 2004 Report Share Posted March 23, 2004 so... what is the correct size then? Link to comment Share on other sites More sharing options...
JustPaus_88TSi Posted March 23, 2004 Report Share Posted March 23, 2004 Factory size is 3.2mm I have Welderwiz's silicone hose, it's 3.5mm...I ziptied everything, because once the hose starts to get hot, they can pop off of the vacuum port that it's on... I'm VERY pleased with Welderwiz's hose... Link to comment Share on other sites More sharing options...

JustPaus_88TSi Posted March 23, 2004 Report Share Posted March 23, 2004 http://www.starquestclub.com/index.pl?boar...rname=Welderwiz Welderwiz is a member here. I'd PM him, the hose is $.95 per foot and $6 shipping. He's in California... To anyone reading this in the future, don't quote me on that price . He has black, blue and red...
