Im trying to get my 91 5.0 running. both the fuel lines were cut but Im not sure which way they hook back up, I thought that the line with the bleeder on it was the main supply, but Im not sure if the main supply hooks stright up to the rail or what. does anyone have a diagram of how they are supposed to hook up. I had to get some quick cupplings to hook them back up but my injectors are getting fire but not firing. Please help..
