I am not familiar with the V8 but the M54 uses a similar line in that location to provide venting for the fuel pressure regulator which because of design updates, no longer uses manifold vacuum to regulate fuel pressure.

Isn't that just vacuum hose?
I think 11747797082 or 11747797177 will do the job. |

It's the vacuum line that connects from the intake hose to the brake booster.
On my 4.8is n62 the line goes inside through the ignition wiring box and out the back and into the strut tower to the brake booster. Mine is in pretty bad shape and want to replace it as well but couldn't open the ignition wiring case in fear of breaking all the tabs. Sent from my iPhone using Tapatalk Pro

My GUESS is that it is the fuel pressure regulator (part of the fuel filter) vent as others mentioned above. Basically it just lets a very small amount of gas vapors go somewhere pretty safe, and into the intake at atmospheric pressure is pretty safe. To really confirm, if you want to, you could find the fuel filter and blow compressed air through the vacuum hose there to see if it indeed comes out this end. If you need to replace it, (and if my fuel filter vent conclusion is right) I agree that generic vacuum hose of any sort should work fine. I used this awesome by-the-meter vacuum line for a few random replacements in my recent overhaul of my M54: https://www.rmeuropean.com/Products/...FG21-V592.aspx And nothing has blown up yet. ![]()

The diagram shows that it connects to the nipple on the intake boot/hose/pipe
N62 have a vacuum pump the the front top timing chain cover for the brake booster. |

16136763993 scavenge air line if as suggested pulling air from the vent on the charcoal filter from the fuel supply. The diagrams don't show where it connects but does seem likely.
It's vacuum hose you can cut and splice in with a fitting if you can get to a good piece.

When I replace my exhaust manifold a couple of weeks back I also replaced few vacuum lines. I used generic vacuum hose (rubber, not silicone) but covered it with PET expanding sleeve, as the lines (feeding the turbo VG actuator) are subjected to slight abrasion. PET is tougher than the OEM cotton covering and also reasonably heat resistant. I used a small section of glue-lined heat-shrink tubing at each end to terminate the PET and stop it unravelling.
