how to set up a car's fuel system??

Question

i have a 1970 dodge charger coming along very well in its restoration. but currently, i have no fuel system. i am not going to get the original gas tank that year one offers, in stead i want to go with a 20 gallon aluminum fuel cell that summit racing offers. but... i noticed a lot of things. in the picture, it shows 2 fittings coming off of the sump, and 2 fittings on the top of the cell im guessing for ventilation? anyways, i need to know where these two -8AN fittings go to. i mean obviously, i need one of them to run to a hose, to a "in-line" filter, to an aluminum line, to another hose and to the fuel pump right? well, i need to know what size aluminum fuel line i need is it 3/8"? 5/8"? etc.. and i need to know why there is 2 fittings on the fuel cell instead of just one? im all new to this and before i spend 350 bucks i just want to know exactly what i need. if anyone can give me a list of the stuff, id appreciate it. [fittings, line, etc..] im running a mopar 383 stock.thnx

Answer 1

very simple, you have a supply line to the carburetor and a return line back to the tank from the fuel pump. as for the size if line, 3/8 line should do fine.
