70 Cuda fuel filler tube with dent

[0791ADUC 1970]

Is this dent in the fuel filler tube supposed to be there?

 

[Mr Cuda]

Yes.

 

[Chryco Psycho]

I agree !

 

[0791ADUC 1970]

Yes.

Thanks Mr Cuda, Is there a purpose for it.

Back splash. That dent makes it hard to get gas in the car, with the newer style gas pumps.

My 70 Cuda doesn't have that dent. This neck isn't dented either.

My 71 is dented

Is 70 a one year only??

 

[Mr Cuda]

I thought the bump was to hold the tip of the gas nozzle in the correct position.

Thanks for everyone’s answers. I bought on from Roseville Auto Parts and it also has the dent in it

I had local Dr Dent take the dent out and it looked good

I saw that someone was making new filler necks for Mustang and Camaro. Does anyone know of a replacement filler neck that is compatible with the current gas pumps?

I've never had an issue with putting fuel in my 70 Cuda so I went out and checked and yeah, it has the dent.

My original 72 'Cuda filler does not have this indent. It's round (tubular man) all the way down. $10 if you want it.

Is this a joke? Why is no one stating the obvious? The filler tube is exposed at this point to objects in the trunk. I seem to recall several times placing rectangular objects in the trunk coming in contact with the support on either side of the tube. The base of the tub often has scratches from these objects. It has long been my belief these tubes are dented from use, by objects placed in the trunk. It never occurred to me the crudeness of the dent was placed there, on purpose, at the factory.

Occam's Razor

What are the odds that a "dent" that is perfectly symmetrical both vertically and horizontally would occur on the fuel filler tube in the exact same location on tens of thousands of Barracuda/Cudas?
And, that the "dent" would occur in a very protected area with factory zinc-galvanized coating remaining intact?

Answer: Impossible odds. The factory filler tube was manufactured with this depression. During acceleration, this depression aids with preventing gasoline from sloshing rearward and upward through the filler tube to the gas cap. 1970 gas caps were VENTED ANTI-SURGE caps which could experience fuel escaping at the cap. 1971-1974 gas caps were not VENTED but the depression in the filler tubes continued, possibly through 1974, even though the chance of fuel leaking at the cap was no longer a concern.

1971-1974 owners should chime in on whether Plymouth removed the filler tube's diamond-shaped depression at some point.

EDIT: @DetMatt1 calls it a dimple. That is a good description.

That makes alot of sense. The one I'm looking at now doesn't seem that symmetrical. But its makes more sense they all got em.

 

[MILOJ]

Wow that picture looks like a fairly big factory dent

 

[DetMatt1]

At one point I had a half a dozen of these things and all but 1 had the dimple.
