On my 1985 carbureted 302, the brake booster line connects to the large vacuum tree like yours does (but located on the back of the intake on my V8). From this vacuum tree, my truck has a hose similar size to yours that goes over to the black "coffee can", located on the passenger's side inner fender.
And/or, it may connect to yet another tree with three ports that is attached up at the top of the firewall, (shown in FordNFishinLover's engine pic) on the passenger's side.
Mine has a vacuum hose running to both the coffee can and the firewall-mounted vacuum tree. Check both places and see if yours has a vacuum hose there.
Alright checked and the firewall tree is all filled with vacuum hoses already. Along with the black "coffee can". Behind the carb and infront of the firewall seems to be some sort of aluminum vacuum booster of some sort, its connected to the manifold I believe and seemed to have an open spot for a vacuum line. I ment to get some pictures but it got dark to easy, managed to snag a pic of the vacuum line sticker if that helps any.
Does anyone know of a guide to safely remove all the unnecessary lines to clean it up? I've removed the ac and smog pump and would love to get rid of all the junk everywhere.
