Help with Replacing Fuel Tank

Thanks in advance,
I started ordering a new fuel tank and associated parts and realized there may be a better way but I;m not sure which route to go. 1971 Scamp V8 with a four vent fuel tank system. I've dropped in my mild 360 auto. What sort of vent system should I use? Do away with the four vent tank? If so what to use? Sorry but I will need sorta detailed instructions as I'm an amateur builder. Thanks again.
