Default 1979 F150 Ranger

Good evening fellow Ford friends. I have a 79 f150 4x4 with a 400m motor pand love my truck. Coming home from camping trip this weekend she died twice on the freeway. I had here towed home. When I looked under hood I saw some smoke coming from back of motor. I thought maybe bad egr valve. Today after removing egr valve I notice this part -picture attached, does anyone know what it is?

thanks for any input.
