Filler neck leak at an angle

[hgeranium]

I just got a full tank of gas, and a few minutes later I happened to park in a spot that had the left side of the truck angled downward. When I came back out I noticed it was leaking gas from the filler neck. I would think it can only leak at such an angle if the fuel neck is rotted out on the top side. After I moved it to level ground, it stopped leaking. 

 

I opened the gas cap and I saw the gas inside the filler neck because of the steep grade but I am wondering if it’s OK to drive for the time being? I’m sure it’s been like this for God knows how long but I just want to make sure. I’m about to move in a few days so I don’t have time to do truck maintenance unless it’s absolutely necessary. Maybe just keep away from parking like that and replace the filler neck once I’m settled in?

There’s a vent on the fuel filler neck, right? Is it possible that the truck was slightly overfilled and it was leaking out of that?

I had this happen to me. The hose clamp for the filler neck was loose. I also changed out the filler neck and vent hoses out of precaution. The Comanche specific ones are not available but you can cut Jeep Cherokee ones to fit. They are the same diameter just longer.
