My 72 240 had su carbs , on the top of the carbs there are two hoses coming out one is from the fuel rail and the other goes to the factory aircleaner . When I try and start the car fuel pours from the rear carb where the hose goes into the aircleaner ,I have tried to insert a pic . not sure if it worked. These are the only to fuel style lines from the top of the carbs . And only the one closest to the fire wall is doing this . As a bit of info the car hasn't been ran in about two years , I just replaced all of the ingition and starter < thanks to all who helped with that issue> and does have the smog pump hooked up <which I want to remove with all that crap > Please any helps thanks Jeff
