69 b body repop fuel tank

I've read the 2 fuel tank vent lines may be reversed on the repop fuel tanks. Is this KNOWN? I am dropping fuel when I drive DOWN my driveway to the drivers side of car centerline. my vents are in the factory correct positions (Short vent more inboard than the longer vent tube), but if the repop tanks are wrong then the short vent needs to be moved over to the vent tube that is more outboard (driver's side).
