Default check valve in fuel tank vent line?

How important is it really?

I'm running a new vent line, and the check valve seems to be inoperative, very little flow EITHER direction. It rattles, but VERY little air flow.

Do I need to order another one, or can I just ditch it?

What year and model of bike? I suspect that valve is something to do with EPA regulations on emissions and stopping fuel spillage.

It doesn't stop overfill spill.
I Had an auto shutoff nozzle malfunction and the gas overflowed and it comes out of the the vent tube.

The bike is an 03 sportster.

I didn't realize it yet when I posted the question, but the end of the tube terminates into the frame, right behind the battery.
