So this is what the gasket under the cap looks like. Theres two holes that lead to small pipes down into the tank which I assume make it into the overflow tube. As you can see, one of the tube holes has an additional hole next to it thats not connected to anything but open to the tank. You can see theres a small metal passage drilled out of the billet aluminum cap part that connects those two for some reason Im guessing. Also where gas is probably getting in by, but seems like its specifically designed that way. What should I do?

Where you have circled if you look inside the tank it meets a tube. Directly 180 across there is a second hole with an aluminum tube all you need to make sure is your aftermarket cap holes are clear and meeting up to both them holes/tubes.

Yup. I had them lined up originally but i just undid it all and redid it in case there was any problem. Honestly, dont think that's fixed anything but we'll see. It's odd that the other pipe hole doesn't lead to anything right?

WHS the top hole is completely blocked
Hasn't been drilled from factory

Yea, that one is completely blocked but there's no cuts or anything in the aluminum to lead it anywhere. You think it's a manufacturer defect?

So this just gets more interesting. I found the oem tank cover piece and as you can see from the pics, the one tube that's completely blocked off on the aftermarket cap basically just has an air hole carved in the side which it looks like just goes to the nowhere but outside air. The other has a complex little red structure which I guess is a type of check valve. I pryed it out to see what is inside and the rattling bit is a ball bearing covering one of the two holes along with some other metalic piece on the other side. Then a funny thin black rubber circle in the middle acting as a nipple. No idea wtf is going on here but looks way more involved than the simple cut-out on the aftermarket cover. Ugh, not sure what to do next to solve the problem.
