fuji4x4 Posted May 2, 2020 Share Posted May 2, 2020 I've recently done the weber swap on my 84 ea81 and while deleting the vacuum hoses I noticed I have a diaphragm attached to the top of my intake manifold that I dont have on my stock 81 gl. What is this for? The metal "L" used to contact the throttle bracket on the Hitachi. Link to comment Share on other sites More sharing options...
