Yes, need to remove both the hoses connected and check if stuck open.

I shall check that out might be plugged up cause I live on the dempster highway gravel road
Customer: replied 2 months ago.
if it's stuck open it's no good ?
Expert:  Gunvir Singh replied 2 months ago.

IF stuck open, fuel vapors will get in the intake and give hard to start condition.

Customer: replied 2 months ago.
Ok but yuh I got a air lock hard time fuelling my truck up
Expert:  Gunvir Singh replied 2 months ago.

There is a procedure to check the blockage in the system.

Expert:  Gunvir Singh replied 2 months ago.

1. Remove the hose from the tank to the charcoal canister and remove the recirculation tube from the filler neck to the top of the tank. Try to fill the system, if the tank will still not accept fuel, replace the whole tank assembly.

2. If the tank does accept fuel, then reinstall the recirculation tube and recheck. If it does not take fuel, then the recirculation tube is plugged or restricted.

3. If the recirculation tube makes no difference, then the evaporative system needs to be checked for a restriction. Start by removing the vent coming off of the Evaporative System Monitor (ESM) Switch assembly. Check each line or look for a plugged canister.

Can't blow threw it anyways
Expert:  Gunvir Singh replied 2 months ago.

If there is no air passing through, need to supply 12 volts at the connector to make sure its not stuck closed.
