I am having an awful time finding the fuel line to go from mechanical fuel pump to the carb. So what Im going to do for now is just install some barbed fittings into the carb and fuel pump outlet and connect them with a good quality rubber line until I can bend myself a steel line when I have time. My question is, what size fittings would I need to install for the pump and the carb? For clarity it is a 1984 v6.
