I just filled up my tank on a hot day and then drove a while and parked at a friends house. A little while later I noticed a little bit of gas was leaking from a tube on the front passenger side of the gas tank. Is that an overflow tube or did something get disconnected on my car?

Just double checking. Haven't seen this before. Haven't had this car for a while.

Thanks

 

Check your vent lines for cracks. Or it could be the seal on your gas cap.

 

That's most certainly a vent tube. There might actually be two of them right next to each other. My '67 Delta has two. That tube should most likely be clipped up against the body under the car above the gas tank. If you can see the tube by just standing next to the car and peering under it, then it has fallen off its clip.

There wouldn't be any such thing as an overflow tube because that would suggest that allowing excess gasoline to leak out onto the ground would be an expected occurrence and part of the design of the tank. With radiator coolant? Yes, before the age of the overflow tank, coolant was just vented to the ground. At least coolant is water-soluble and not flammable.

But gasoline? That would have been a very dangerous design to have cars routinely putting gasoline on the ground.

 

You should have 2 vent hoses coming from the upper RH corner of your tank. These two hoses connect to a plastic fitting that has a piece of foam in it. This plastic part is clamped in place against the underside of the car and sits a little higher than the tank. There's a small bracket that is screwed to the bottom of the car that holds the plastic part in place. I would check all the parts involved here in case something is missing or is damaged. While you are under there, it's probably a good idea to replace the hoses in the middle that connect to the metal fuel line(s) that run up to the fuel pump. Depending on your model of car, you could have 1 or 2 lines running to the fuel pump. Attached are 2 photos that show the vent pieces and the fuel lines on the tank and this is for a 69 442. The cat gave his seal of approval.

 

Thanks for the pics! I'll definitely check all that out next time I crawl underneath my car.
