I noticed my fuel pump on my 71 350 was leaking so i got a edelbrock pump from summit,I haven't installed it yet because I'm not sure if I need the bottom feed plat. I looks like it's going to be a tight fit, I also got a new steel braided fuel line and i'm not sure what fittings I need. the pump is 3/8 inlet & outlet, the fuel line is 5/16, not sure what the -6 an means. Also the rubber fuel line going into the pump from the tank is in really bad shape, how hard is this to replace? size? length? fittings? any help would be great guys...
