IWE Vacuum Hose Replacement

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,
