Hello,I have a 1978 Mercury Grand Marquis,351M,5.8,and there is the coffee can looking vacuum reservoir on the drivers side of the vehicle on the fender well. There a vacuum lines going to a vacuum junction,2 lines to the intake,and I need a diagram or picture of the two vacuum lines,one going to the coffee can vacuum canister,and it looks like another one going into a canister,which is hard to see as it in in the fender.Both have on line going into a valve,and 2 line coming out of the valve,like a one way vacuum valve.The single line is in the vacuum junction as the main large line off of the intake manifold goes to this,I know the single lines plug into the vacuum valve to the way out valve,but the 2 lines coming out of the valve,how do these go,one to each vacuum reservoir,of one in one and out to the other,then to the firewall,I assume these are for the manual air conditioning module and possibly the vacuum operated parking brake?Can anyone send me a diagram,or a picture?PLEASE,,My father installed a intake manifold gasket,and so far I believe I have the rest of the vacuum lines on the motor OK,as there was NO emission sticker on the hood,just looked at the bends of the hoses and the size,and poking on the internet,but I do not know why he disconnected these lines.(((((((((So from the valve with the main vacuum line from the intake)))))),(two single lines,off the main valve,each with there own valve going to to lines,and one of which goes to the coffee can and another to a can or reservoir in the fender,cab just see to plug it in. May have.I an sorry if I an rambling,I am confused and want to get Dad's car on the road.The &* is in pr-emo shape,was my Mothers's before she passed a few years ago.ANY HELP,IDEAS PICTURE,DIAGRAM'S WILL BE DEEPLY APPRECIATED FROM MY FAMILY AND FATHER.God Bless to you all.Mark Bradley,,,Cedar Lake,Indiana.
