Over the past couple years I have owned my EVO, I haven't had much of a problem with my vacuum hose. Only a couple pin sized leaks that showed up during boost leak tests.

My intake is off getting ported, and instead of running straight to NAPA to get a roll, I thought I'd check to see what everybody's preferences are.

Thanks!

**3/23/12 Update**

After a bunch of research I decided to buy a bunch of hose from BoostControllers.com

It is 4mm "MAGNUM" hose, and is astronomically thick (3.2mm wall), but yet just as pliable as standard hose.

Yes I got 40 feet of it, lol:




At only $1.07 a foot, it is really hard to beat.

 

Heavy Wall, 15' 4 mm I.D from oomphlabs. A bit expensive.

whatever i can find that works at ACE hardware :-(
small college town... im very limited.

 

stock one works for me now lol

 

Ive replaced some of mine with STM's vacuum lines they sell, excellent stuff.

 

Silicone vac line is the way to go, a little more expensive but will last a much longer time

Thats what STM sells, fyi

 

Thanks guys! For those of you still looking, It can be found here.

I want to get some new vacuum line too, what is the stock line sizes? I see there's 3, 4, and 6mm....Which is used for the intake mani 3 or 4? and I assume the other bigger intake port would be 6mm? I can't spend $50 for the combo kit

 

i wish someone or a shop offered a kit that replaces all the junk rubber factory vacuum lines with pre cut silicone lines.

that way you just pop a line off and replace with new line. its not so much the length that gives me trouble, its the diameter. i never know what diam. to order

 

4mm is what the majority of vacuum lines are. I do believe there are a couple 6mm hoses also.

If I still had all the factory parts installed I truly would consider taking a couple hours to do this.

 

Look at post #7 from Emery, click on the link and look at the hose kit, I'm assuming has enough for to replace every line....on a stock evo at least or depending on bov location and whatnot. I want to get some and going to run seperate lines to the bov to intake and turbo/mbc since someone is running everything on one line and it is hindering the response of the bov and causing stuttering/driveability issues.

 

Napa or Advance hoses ftw! Been using them for years with no problems

 

$2.99 blend-in black wiper fluid hose

 

Wiper fluid line should not be used as vacuum hose

 

5/32" is the same as 4mm so for those who buy from Napa / O'Reillys that will make it easy to find
