Fueling up a 1963 Ford Falcon

The maximum allowable delivery rate for a gas pump is 10 gpm. Some are significantly less as in 2-3 gpm. Try using a different gas pump or several different ones. If you always get the same result look to something in the filler tube Ie., kids put something in there etc. Also can check for a kinked fuel filler tube or the tank vent line kinked or bent.

Forgot to address the gauge. This is more than likely a bad wire connection at tank or somewhere on that circuit. Or possibly just a bad sending unit.

I'm not sure about the '63, but the input for my '65 is positioned so that I actually have to pump up first. If the '63 is like that, then yes, you have to pump really really slowly to get the tank filled up. There are kits which you can buy to relocate the filler neck which helps, so I've heard. ... like this: http://www.dearbornclassics.com/fuel-filler-neck-relocation-kit-falcon-1964- 1965.html

Agreed, My 64 was difficult to fill 15 years ago-and we all now how much fuel nozzles have changed since then- I can only imagine it's gotten worse

I would check your fuel gauge,first..-It"s very easy to do-just ground the wire,going to your sending-unit,turn the ignition switch,to the on position,and watch the gauge..It should go all the way to the full mark..if it does,then,your sending unit is shot..if it doesnt-Then,your fuel gauge is ...

I also had a problem fueling my "63" Falcon. The filler neck not only has a sharp angle down but also is angled off to the side. i installed a Mustang gas tank which is angled down but not sideways. I still need to fuel up slowly but i haven't had any problem with blowback. Plus, the Mustang tank is 4 gallons larger. The gauge is a separate issue however. I am actually having the same issue myself with mine but there are several good videos on Youtube to help diagnose the problem.
