Only reasons the vent would leak fuel from it is. (A) if there is a check valve it's

so if there is a check valve in vent it could not be working or the check valve you installed on filler neck isn't working or u I stalled upside down.... when filler neck get full its supposed to make that check valve ball cut off supply from auxiliary tank....you can check this by opening truck fuel cap and if filled to the rim it's not working correctly. BUT!!!! BE CAREFUL IT WILL START FLOWING OUT WHEN YOU Take cap off... now the newer truck like ram with no cap I think you'd have to push open both flapper doors to make this happen...

I have a remote valve in place in my set up. when i get low on fuel I simply flick a switch on my dash and the valve opens to fill my tank. When it is full I turn off the switch, easy peasy
