Got my Marine Demon 650 vac. sec. carb today. My small block Chevy jet boat has an electric pump and 3/8" line I think. I don't know all the names of different fuel fittings and I need help hooking up my Marine Demon to my existing fuel pump. I got a Barry Grant 6 AN flexible stainless dual feed from Jegs. It has a male end fitting. The end of the fuel line going to my current Holley is male also and looks nothing like it. Look at the pics of my current set-up below and tell me what I need to hook the carb to the pump. Thanks.
