Hi all,
I need to know if there is any science involved in the little plastic hose that connects the plenum chamber to the vacuum advance, does it have to be a particular bore or a particular material this leads on to where can I get the rubber elbow parts at the end of said pipe/tube?
thanks

Bore size is not an issue but it must not crush under vacuum so if rubber it will need to be thick wall.
Car builder Solutions should have all the bits you need.
