May 2, 20205 yr 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.
May 2, 20205 yr Author I doubt I need it considering half ea81s dont have it but I'm curious if anyone knows
