Some Backyard Wrenching with the Kiddos
#31
The picture you show is correct. The line comming off the brake booster at the white fitting goes to the back of the carb. The white fitting is a check valve that allows vacumn from the engine, to assist the brakes. Thus they are called power brakes. The pcv line usually attaches to the air cleaner housing, with a short hose usually about 6" long. There is a small filter which sets in the side of the air filter housing. The hose form the pcv valve connects to the filter, with a small plastic elbow. It looks like you may be missing the hose for the pcv ? I believe the 71 -73 mustang's had the pcv valve in the top of the oil filler cap at the front of the drivers side valve cover, and the hose came back to the air filter housing from there. I'm not 100% sure but I think so. Hope it helps. if I'm wrong someone else will know. JTS 71`Mach1
