Stop in for a cup of coffee

Hey All... I got a new fuel tank for this 70 Duster...The one they sent me has 4 vent lines next to the Big fuel inlet for the fuel pipe. Original does not have em. Has a vent along side the outer fill tube. I dont see any reason I cant use this 4 vent tank. I'll just cap em off....really want to do it tomorrow, and not return this tank... Any Opinions ????????
