No forcing at all I'm glad to hear about it this way then at the parts counter after a water crossing. Trying to understand how this system works. So looking at the filler it appears the vent is venting to the inside of the cap area? would the gas cap not be sealing this? or are the gas caps not air tight and its sucking water from under the cap or are the tiny holes on the outside of the filler neck the vent holes?
Cool didn't want to seem like I'm a crazy person.
So the small line is overflow return of gas to the tank. Filling up and topping off. Not sure how this ties into the EVAP canister but it seems to.
This is the conversation I had with my dealer parts guys and they are pretty knowledgeable folks.
The black plastic surround with small holes to the outside are fresh air inlets for the EVAP system. That is the larger hose running to the black box and small pump under the bed. If its submerged the water simply runs into the EVAP can that houses the carbon and the pump and a small solenoid. It is the main piece to try and keep dry.
In my case this happened during winter and the water that had gotten in had frozen and the small pump was all locked up. Brilliant on my part. But whatever I know the issue now and can fix it.
But I'm unsure if simply moving that hose to a different breather would have an effect.
Easy enough to try and saves you a head ache as for moving the filler. Let me know if that works. Be cool if it does.
