I have a gl with an ea81 motor the engine has been rebuilt but I have no idea where all of these vacuum hoses go to. I can't seem to find more information than what's on the underside of the hood which for some reason does not cover every hose. I'm aware that a Webber would be the easier way to go but I can't afford to that right now and I need to get it running. ANY help would be appreciated thank you.
