Fuel tank lines

[Chopperdriver]

Do I need to plumb in all 4 vapor lines from the accumulator to the tank or can I run one and cap off the other three? I’m not worried about collecting vapors I just want to make sure the new tank is properly vented. 1970 300 original California model.

I have installed 4 line vent tanks in 2 line vent cars. Simply plug off the the unused vent lines w/ gas rated caps w/ clamps and you are good to go. Do not use plastic caps as they will deteriorate and leak.

Thanks David!
