Thank you all.
Just giving back to the community exact measurements from my N54. Should be the same length regardless of body type E90/91/92/93. But these original lines are from an E93. I bought 15 Feet of "Verocious Platinum Cured Silicone Vacuum Hose - 3.5mm Blue" from verociousmotorsports. Ended up with 5 Feet extra. But next time I will probably color combo with White Silicone Lines
I divided all the lines into 7 sections. In order of difficulty. 1 being the easiest. 7 being the most difficult. This is the order I recommend but do what you want! I am rounding up values since they are not perfectly straight, I was fighting with some scotch tape to keep them in place to take pictures.
Section 1 - Near Brake Booster Hose = 7.5" Inches x1
Section 2 - Twin Lines Near Oil Filter Housing (They are the same size) = 6.5" Inches x2
Section 3 - Twin Lines exiting the black McDonald Straws on top of Engine connecting to Bottom of both Vacuum Canisters = 6.0" Inches x1 & 9.5" Inches x1
Section 4 - On Top of both Vacuum Canisters = 16" Inches x1 & 20" Inches x1
Section 5 - Nearest Boost Solenoids = 1.5" Inches x2 & 5" Inches x1
Section 6 - Front Turbo = 15.5" Inches x1
Section 7 - Rear Turbo = 20.5" Inches x1
Result:
