i am having trouble with the vaccum lines on my 1977 f-100. it is a 3 speed auto, with the 400 engine. or 6.6 litre. this is a canadian truck, not sure if it matters. the truck has none of the tomato juice pollution canisters,that most trucks have. my problem is i have a air cleaner with many ports. 1 port for the crankcase vent hose, i have that one figured out. pcv valve, figured that one. now,there are 2 diaphram type things clipped into the body of the breather.these 2 diaphrams are plastic. one is green, one is white, nothing is plugged into these diaphrams.they each have 2 nipples on them. in the top of the air cleaner is another diaphram, this one is metal, also with 2 nipples. on one nipple there is a hose that goes to the air cleaner duct motor. can anyone tell me what vaccum lines get plugged into these diaphrams. does anyone have accurat vaccum diagrams

Thye port you're refering to is generaly used with the E G R Valve located under the carburator and the flaper in the neck of the air cleaner . To be truthful with ya , I can't remember if the factory manual has what you need or not . I can send it via the mail. Let me get a printer that actualy prints in the next several days and themn I can actually help ya .
