As Jeff said things are slow on the boards lately. I personally would like to get to next year already. The last 13 months has really been a struggle after losing our 22 year old Son while serving this country as a Marine. He was also an important member of our race team and a large void is in our daily lives.
Enough of my problems now back to yours.
I use a black press on hose (XRP) for my vacuum lines. It has a flex steel core that will not crush but is flexible.
We use it for all our fuel, Oil and vacuum hose needs.

Let me know if that is what you need.
