replacing rubber vac lines with metal

[Billy Mild]

I have thought about replacing all the rubber lines with silicone lines. The issue I have is the small canister under the manifold that has a special 90 degree bend with 2 vacuum fittings on it. I may just use a T fitting with 2 lines. I used silicone tubing on my 944 turbo and never had an issue with boost or vacuum leaks.
