Has anyone found a source for the metal braided vacuum line similar to what is used for the factory PSE vacuum lines? I could use about 3 feet of it. Needs to be very heat resistant just like the factory. High temp silicone won't hold up to what I need, the stainless stuff I have found is more for looks than function, and the OEM stuff isn't long enough and is very expensive.

Are you running fluid or air? Under negative or positive (or both) pressure? What's the inside diameter?

Will something like this work? Braided Bronze line

Vacuum line, air. Same diameter as the PSE line. It is for a different valved muffler that needs longer vacuum line.

Have you tried a racing shop? Something like this:

Use some HD Silicone made for vacuum and put some fire sleeve on it. I've done some terrible things to that stuff and held up exceptionally well. I've even used it on some 991.2 custom valved stuff we've done here.

While there was good advice in this thread, I figured I would update it for sake of completion.

The OE vacuum line for PSE is a 4AN (3/16 or 5mm ID) stainless braided teflon/PTFE lined hose. I was able to buy it from a local hydraulic hose shop for $8 a foot... Porsche charges $85 for an 8" piece.
