I am in the process of fixing my last problem (see 91 GT Problem thread) which turned out to be the rubber hose connecting the fuel pump to the hard metal line inside the tank. My question concerns the hard metal return line inside the tank, on the fuel pump frame. On the end of that line there is a redish colored rubber piece. It is about one inch long and kind of crimped down on the end. I imagine the purpose is to control the spray of fuel returning to the tank. My problem is that this piece was torn and just barely hanging on, well was barely hanging on until I tore it the rest of the way off. I don't know what this part is called, where to get it, or if it is even important enough to worry about. I would just do without it, but I figure if FoMoCo spent the money to put it there in the first place it must serve some purpose. Any help is appreciated and thanks in advance.
