Write up: How to relocate your brake booster hose
So this is my first write up so go easy on me. This mod is purely for aesthetics. I hate the look of the hardline crossing the wall so this shortens it and tucks it behind the UIM.
Important things to know
-The vacuum supply should be tapped after the throttle body
- there is a check valve so the brake booster doesn't get pressurized
Supplies
1/4" npt to 3/8" barb
3/8"barb to 3/8" barb
tools
pliers
dill/drill press
7/16" drill bit
1/4" npt tap
1/2" socket/rachet (optional)
welder or jb weld or nipple cap
Fittings can be found at home depot. it was less than 5 bucks
first remove the hardline. replace the hardline with the barb to barb fitting to connect the hoses
now get a 7/16" drill bit
I chose to drill in the back of the UIM right above the 2 vacuum line sources (i cut mine off)
now get the 1/4"npt tap
because the UIM gets in the way of the tap tool i used a 1/2" socket, and tap all the way through (use cutting oil, i just used some wd40)

now sit back and admire your threaded UIM!
wrap the fitting with some teflon tap and screw the fitting in (15mm i believe)
(white-ish hole on the bottom, the dark hole is from an emission delete)
Now connect the hose to the fitting and slide the clip over the hose to secure it.
Lastly you can either weld, jb weld, or cover the vacuum source with a nipple
enjoy! (sorry no final pic, engines still apart)

Only reason they put it there is it's a short one small rubber hose run to the brake booster on a RHD car. The 2nd gen turbos have the brake booster hook up on the back of the intake manifold near the throttle body, similar to where Ben put his.
BTW, you want to make SURE you have a solid connection, if this comes off or fails you'll have a VERY hard brake pedal and this can be a big safety issue. Also, use the OEM hose, the hose on the brake booster side has a built in check valve.
