There are a couple of small real twisty vacuum hoses under the connection panel on top of the valve cover under the black cover on my 240. I know that they are not available today. I tried tie wraps, but my smallest are to thick to fit in there. I thought there might be some very small wire type ones? I might just use some wire strand and pliers...like a bailing wire fix. I was seeing a little smoke coming up from the under the cover from my tester.
