This may be a silly question, but how do you replace the rubber ends on the hard plastic vacuum lines? I had one come apart and the rubber vacuum hose I have (Volvo original) fits the manifold fitting perfectly but is to large an ID to grip the hard plastic vacuum line. I know I can just replace the whole line with rubber, but I wanted to keep the plastic line since it is the one that goes to the ignition module (routes under the engine). Let me know what your repair hints are. Thanks.

I've used some of that liquid rubber stuff that they sell for use for sealing electric fittings, it works great.
