I have just completed my retrofit of the xenons. I noticed a hissing noise developed thereafter. Upon doing some research on the forum, I've concluded it's the vacuum line that is used to work the 3-stage manual leveling for the halogens. It's hissing because it's no longer properly connected to anything that requires the said vacuum.
As xenons use self-leveling (which I do not plan to hook up), what have all of you xenon retrofitters done to stop the hissing of the vacuum line?
