As some said, silicone hoses are provided by STILLEN and can be used to cover the AC lines (OP simply forgot to do so as he mentions it in the post). STILLEN sends you TWO silicone hoses. You only need to use 1 for vacuum lines (cut in two pieces) as the distance from the G3 tubes and vacuum lines are VERY close. The other silicone hose can be used as an A/C line cover. Find yourself some double sided tape (in my case, I used 3M VHB). Take a look:
Step1
Put some double sided tape (I recommend VHB for their durability and bonding properties)
Step 2
Cut the 2nd (provided) silicone in half and put it on top of AC lines.
This will outlast your car.
Josh, if feel that you need to edit the instruction manual or use ANY of my pics above, I give you full permission.
