Hi, I am planning on fitting an anti run on valve into the vacuum hose between brake servo and manifold. I was planning on replacing the vacuum hose whilst doing this, would it literally just be a case of pulling the old one off and fitting a new one with the valve in place (plus wiring)? Would anything need to be blead? Also, the hose currently is the standard black, almost brittle vacuum hose. Would I be able to change it to a silicone vacuum hose?
Thanks
