Does anyone know how to remove and reinstall the fuel injection rail on an S4 Spider? Specifically The repair manual says to cut the short fuel hose between the rail and the injector but is vague on how to reinstall them. Has anyone ever done this? Also any idea how to remove a stripped out socket cap screw holding in the injector? Are these actually in the manifold so if I remove the whole manifold I can drill it out? Lastly I know the fuel is under pressure; how do I release the pressure safely or is this not an issue? Thanks very much if anyone knows how to do this.
