Hi Everyone,

Another question. I just filled up and gas is leaking out of what I guess is an overflow tube. This only happened once before. It does not happen regularly after a fill up. Any thoughts?

Overflow??? You mean the vent? OMG, Ford never designed a car to dump excessive gasoline. The vent tube (if your car has one like my Galaxie) raises high inside the trunk then exits outside, next to the filler neck. They use the height of the trunk as a 'trap' so air can equalize pressure in the tank but liquid stays down.

Hi,

Thanks for responding! Yes, it would be the vent. Would you know what causes gas to exit thru the vent, down the bumper and eventually on the ground/

Something is terribly wrong because a condition like that in a new car would have initiated a major recall. You must have a broken connection or a tube that has rusted through.

Carefully follow the tube and use all your senses as you go. Move it around. Use a flashlight.

Is there a strong odor in your trunk? Is this happening on hot days? C'mon, give more detail because all I know is what you report, which is; this is the second time the vent tube is leaking after a fill-up. - Dave

Hi,

It's a rubber tube abot 3/8 " diameter. No smell in the trunk. Yes the days were warm but nothing above 80.

Even though you have a vent tube make sure your gas cap is also vented.

Hi John,

Thanks for your advice. I sent an email to Stant. They have several types. It looks like the most popular has a red lever on it.Part #10331. Do you think I should get that or just a regular vented gas cap?

Your fuel tank vent should be small-diameter steel tubing (like 3/16" or 1/4") not a rubber hose. The only rubber used would be at the connections with clamps.

For the fuel tank cap, Rockauto.com sells STANT 10646 caps for under five bucks. - Dave

There's a rubber hose that connects to the vent fitting and sits in a groove on top of the tank so it's not crushed between the tank and trunk floor.

Oops. I meant fuel fitting not vent fitting. As Dave mentioned there's a small metal vent tube near the filler neck.

Have you located the leak yet?

I do not suspect the fuel line because the suction would cavitate rather than leak. My understanding of the problem is that fuel leaks out onto the pavement.

It's important you find the leak ASAP. From here, I can't see how rusted your fuel line is or how rotted your connections are. So, it's up to you to locate the leak. Let us know what you found. - Dave

Talked to my mechanic today. He only has one guy at the shop that can work on older cars. I'm schedule with him next Wednesday.

Thanks to everyone who commented. I now have a metal overflow tube and vented gas cap.Hopefully no more problems. I also have 2 pr. of Thunderbird valve covers, goldish in color. Not sure which motor they fit. If anyone needs these, let me know. Not sure what they are worth. Also located the upper interior windshield molding. I appreciate everyone's suggestions. :D

Turns out Rock Auto sent me the wrong gas cap.It either was not vented or did not work as it should. Had gas flowing uphill out the filler neck. They were apologetic and shipped the correct one out (they say) yesterday.
