Default boost solenoid vacuum hose replace choices - 03-21-2018, 04:19 PM

Replacing the boost solenoids and want to replace the vacuum lines as PM.
What are you using to replace the tubing? Silicone has fun colors but will it collapse? factory type woven? Looks like 3.5mm ID? Thanks...dmc

Found an old thread...looks like silicone is the preferred option and 3.5mm ID

Silicon works great, that's the go to choice for replacing the vacuum lines. I'd recommend replacing all of the vacuum lines.

I guess I'm old school I went to FCP Euro and ordered the 3.5mm braided vacuum line pretty cheap and it's oem. Get about 15 feet.
