Got all my vacuum lines for the a/c heater connected except one. It is a solid black line with a straight rubber connector on the end. It is the only line with a straight connector. It has a broken black plastic male connector in it and the other end of the connector has a red rubber hose on it . this red rubber hose was longer and had some sort of factory molded bend in it but it fell apart before I could get a picture of it. It is not the vac can supply as that is a black and gray line that has a firewall grommet attached to it. I have attached pictures . Thanks 1978 c10
