It's been problematic for years but as of about 2 years ago, with the local vapor recovery nozzles here in WA, I have a LOT of trouble trying to dispense fuel into my 69. It "clicks back" almost immediately, and it takes a long time to even put $10 in the car. Very frustrating.
I've tried the obvious (different angles and flow rates) but am wondering if anyone else has run into this lately and if there's a good solution I've missed!
Might have to take a jerrycan with you and then dump that in 5 gallons at a time. Bit of a hassle but will be quicker and doable. Wonder if an extension like a funnel would fool the pressure sensor.
Well my '73's is behind the plate as well and I have had the same issue as Dave since the day I got the car, about 14 years now. The problem is the filler neck tube does not have enough of an angle drop on it and the fumes back up quickly shutting off the flow.. The only way I have found to fill up gas is to barely insert the nozzle into the filler tube and be careful to not ask for maximum flow so gingerly squeeze the trigger about half way. As Dave suggests this takes a very long time. On my car you cannot use a funnel and a Jerry can because the angle is so slight the gas just spews on the ground out of the funnel. I have a flexible hose that I use the curl up above the bumper then insert funnel then that will work.
Another thing I can't allow is a gas station attendant to fill up the car. First they can't find the filler tube then secondly they don't know how or are incapable of putting the cap back on properly which results in gas just rolling out of the tank due to the almost level filler tube.
I presume the filler necks in my 70 2+2's & Parisienne are basically the same as Dave's 69, and I've never had a problem. I've driven them through most of the western states, including California.
I wonder if the vent in Dave's fuel tank is operating properly. It's connected to the top forward corner of the fuel tank on the passenger side, and goes up into the trunk, than back down again to vent to the atmosphere. It's worth checking.

The worst car that I've ever had to put fuel in was my 58 Plymouth and 58 Dodge. Both had side fuel fillers and for some reason a full tank wouldn't shut off the nozzle resulting in me wearing a lot of gasoline.
My Impala has a similar problem. I have found a couple of local stations that have an area outside of the concrete that allows the front end to drop down sticking the rear up. Still have to slow down the filling as the tank fills. I usually slow down after 70.00 when the fill up goes to 100.00.
I sometimes have to wait in line for my preferred spot.

Try the advice seventy2plus2 gave you.
In my situation that vent tube was full of spider nests an other various
Insect egg sacks .
Easy fix
Unhook the rubber line where the vent connects to your tank
Stick a blow gun up inside and blast it!
Rust , insect DNA,Jimmy Hoffa gravel,and anything else that is in there will come flying out!
Watch your eyes!
If yours is rusted out or damaged
You can find new ones or use your old one as a pattern and make a new one.

I'll definitely check the vent line - for some reason I'm now having some weird deja vu about pressure building up behind that cap, which it shouldn't in 1969, right?
I know the tank line comes up into the trunk, as I've seen it, so I know it's there, but I wonder if it's plumbed wrong or something? I'll have to check. How though? Blow air into it from outside?
The vent will be a 5/16" rigid line with a rubber connection into the tank. Undo the rubber connection and blow out the line. While you're at it, stick a wooden skewer or something into the tank just to ensure that inlet isn't blocked.

Another thing to be careful not to do with those old U-shaped loop vented tanks is to overfill. Once I really filled my tank, then I parked on a slight downward slope on a hot day. Fuel was forced out the vent and loads of gas was all around under the car. I was terrified and just dropped the car into neutral just to roll it away without starting it. One spark and it could have been "boom!" Even static could have triggered it.

I found a pump at a different station I was able to make work - it's a newer kind with a chip reader that also starts the flow "slowly" and ramps up. In order to get it to fill, I had to keep the filler neck like this so that the fuel was shooting straight into the tank and not into the neck at all.
And if the picture is upside down blame Activeboard! The fuel would actually all run out if were upside down like that...
