Just to help out on the E46 side, we've done a lot of research lately into figuring out exactly what vacuum tubing (one material), hoses (multiple materials), and pipes (rigid) and vacuum endcaps to replace.
The Realoem diagrams for the M54 are notoriously inaccurate; so we also corrected them as needed.
We also are working on the lengths of tubing, hoses, and pipes to buy, and from whom.
Since nominal prices are horrendous (over $300), we found a great supplier of Viton vacuum tubing at good prices also (around twenty five bucks or so, depending on your selection).
If you're interested, see the following recent threads on the E39 side of the house:
- How to locate all problematic vacuum tubing & vacuum endcaps in the E39 engine bay (1) & where to get new vacuum tubing & endcaps (1) & what SAE sizes to get for all the M54 engine vacuum tubing (1) & correcting the F-connector errors in the realoem diagrams (1) & finding the ends of hard-to-locate vacuum tubes (1) & how the sucking jet pump actually works to multiply manifold vacuum to the brake booster (1) & sorely needed clarification on how the M54 CCV vacuum port works on the E39 M52 CCV valve connection to the fuel pressure regulator connection (1)
All these threads could use your input.
