The nozzle has the mechanical feature to shut itself off for safety reasons, like people walking away from the car. The quote I posted suggests it might interfere with nozzle's ability to self-turn off.
If you start bypassing evap lines or plugging them, you might run into other issues with drivability.
If that evap line is blocked completely (you'd have to plug it off) it won't be able to purge the tank of fumes when/as needed, and might start throwing a CEL, dunno how sensitive the systems are. If the vent is blocked on a healthy gas tank/car, as the fuel level drops, it'll create a vacuum. If the vacuum is strong enough, it can stall the engine. Dunno if the gas caps on these have vents or not.
Not my strongest area. If it's a beater or something done as a temp. bandaid fix, it's up to you. For long-term drivability, I'd just fix it.
