93 5.0 lx . this is a black tube that runs to the back of the upper intake manifold. There is a red one that plugs into the port next to it. The black one that i broke seems to go to the egr system. It is a small fragile (obviously) black air tube. Not a hose, its a small tube. I have know clue what its called and where to get a replacement. You cant buy this at the hardware store. It has adaptive ends. Thanks
