I discovered my '66 Barracuda project car doesn't have a gas tank. I now have one (+ strap & sending unit) on order. In the mean time, I'm trying to figure out how to remove the filler neck to replace the broken piece of hose that connects the neck with the vent tube & I can't figure out how to remove the filler neck to make the repair. I'm also trying to figure out what piece(s) I'll need to attach the filler tube to the gas tank. I have a couple of manuals, but none show an early Barracuda. Can anyone provide a diagram? What parts will I be needing? Thanks!
 
pretty sure its a handful ( 5-6 ) screws on the floor plate, then the 4 screws under the gas cap and its out. might be forgetting something as its been more than a couple years since I pulled one out of a barracuda.
 
I dont think you need to remove the filler neck to replace the hose. I think there is enough play in the vent tube to get the hose off and replace it.

There's a rubber grommet that fits in the hole in the gas tank the filler tube fits through, and seals the opening.
On a Dart, there's a metal plate bonded with a rubber covering where the tube goes through the floor that seals it. They are available from DMT:

Fortunately I have the part you mention & have the grommet and new tank/strap/sending unit on order. I was trying to figure out how to wrestle the filler neck loose (out?) to get it in the right position to attach the rubber hose & line up the chrome sleeve. Maybe I don't need to get it out, but it seems awkward as hell to deal with. I'm gettin' too old for this. :)

On a Dart it's fairly simple, but we Dart owners don't have to worry about the horizontal sheet metal pictured or a chrome sleeve. I just twisted my tube into the tank, and then pulled it out into the trunk. But that doesn't appear to be an option with that sheet metal piece in the way. Hopefully a fellow Cuda guy can help you.
 
On your '66 Cuda, or any big window 'Cuda, the vertical inner steel panel that the filler tube passes thru must be removed if you want to remove the neck regardless of whether the tank is installed or missing. Above that is a painted interior trim piece that must be removed before the inner panel mentioned earlier can be removed as it hides the upper screws for this inner panel. Agree with other posters that one can reach into the void area and replace the hose, however much more difficult on big window cars since you are essentially doing it blind by braille. Also, once necessary panels are removed it is easier to twist neck and guide it up and towards the top of the wheel well void for removal rather than trying to rotate it towards the rear of the car to remove it. Just went thru this removal on my '66 to get it ready for paint. Installation is the reverse - Neck and vent line in first, replace lower inner panel neck passes thru then the interior painted top piece. As other posters suggest this is mush easier on any car with a trunk as everything is exposed and very visible.
 
If you are going to the trouble of removing the filler neck you might as well modify it so you can actualy fill the gas tank with it. Not holding the gas nozzle at some weird angle and holding it at 1/8 flow until it overflows.

I pried that painted (in my case, black) panel up & found 3 Phillips screws holding it in place. They were very difficult to remove (especially while forcing the panel upward at the same time), but a long thin screwdriver did the trick! I'm not looking forward to putting them back in. :)
 
I replaced the tank on my ‘66 three weeks ago. I pulled the six screws out on the top of the tank and the three screws holding the filler tube to the quarter panel. This allowed me to twist the filler tube loose from the tank. I did NOT pull the filler tube out.
Underneath, after removing the strap holding the tank and disconnecting the fuel line, I was able to wiggle and twist the tank loose off the filler tube.
To put the new tank on, I lightly coated the end of the filler tube with Lubriplate to help wiggle the new tank onto the filler tube. Hope this helps.
