IWE Vacuum Hose Replacement

[TomDirt]

I'm pretty sure the oem tubing is made of softer, more flexible rubber/silicone material due to it's ability to cycle continuously.



Plastic tubing used for that application won't likely survive the twisting and flexing as long.

What sizes are the tubes? I’m now in the Same boat, I’ve got a long drive to Alaska in the winter coming up.
I no longer have 37’s, I just need the hose to connects to the hub, but I bought the whole harness, I just would like to run blue heavy duty tubes like this pic I stole, so if anyone know the tube size that’d be awesome, I have a caliper but I don’t trust the numbers,

I don't actually remember. But I do remember that you have to pay attention to both the inner and the outer diameter of the tubes. The inner diameter because you want it to make a tight seal with the actuator, and the outer diameter because the two tubes have to be all close together.

I tried it myself with tubes from Amazon and cable ties. Didn't work well. Then took it to the mechanic and had them use their own proper tubes, but I still had trouble. Apparently so many owners do and installed the Dorman IWE delete kit just yesterday Seems to work well!

I mean, if you're at the point of replacing the tubes, I would just splurge a little more and get the $100 IWE delete kit. It's worth it in the long run, especially when the entire IWE system is so error-prone.

I too went the vacuum hose route. Been good for all a year so far

I'm really surprised but happy for you that it worked out!
