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 ????????
Keep it if you can and don't see any other differences.
Think they even have the plain version?

Only two things really need to check is the tank can vent (is through the cap ?) and the carb can vent.
The 4 pipes is for some variation on the vapor capture systems that got implement in Calif and then the rest of us got it.
