Seems like a hell of a lot of trouble to go to avoid the paranoia of having a couple drops of gas get on your rear panel. Clean it up! Or maybe rig up some sort of bib that will slip over the neck opening so that any spill will roll over the bumper and not onto the car?
Overfilling or spilling into the trunk will be a much bigger mess to deal with.
And we've had lengthy discussion on this forum about the danger of the gas tank being the floor of the vintage Mustang trunk.
persoanlly i wouldnt think its too safe to modify the fuel inlet to inside the trunk.
imho in your case youd be better off refilling using gas cans the nite beofre you go cruising.

O/T a bit, but for some reason my car is a pain in the backside to fill. I'm in MASS and I have a 67 GTA w/the GT hinged filler and it takes me a good 15 minutes of bent over stop & starts with the gas hose to get 15 gallons of gas in the car. I met a guy in Utah that did the modification to fill the tank w/the trunk open. It did not look like the perfect solution, but it worked.
Maybe if I took the hinged filler off it would be easier.
Unless you are building a competition show car and you need to eliminate the clutter, please don't do anything as ridiculous as putting a filler INSIDE the trunk. You are just asking for trouble. Fumes, spillage, venting, etc.
To start with, if you have experiencing fueling issues, get that fixed 1st. Secondly, the fuel systems in these cars are "vented", and while placing the fill cap inside the truck area is doable, there is a big difference between a vehicle equipped with a fuel cell and one that is not as well as a sealed versus vented fuel system....and yes, there are federal regs (going back to the 60's) that can be used by both law enforcement & your insurance company against your best wishes in the event something goes wrong- and there are many issues that can. Most of the auto-enthusiests in multiple venues going back decades have promoted the removal of fuel systems from the vehicle interiors (unless it is for show, etc)- this is especially true for pickups of the era, where the fuel tanks were mounted inside the cab, behind the drivers seat area. In the event of a rear collision involving the fuel tank (which in the stangs, you have only a few inches before it becomes involved), with the fuel filler/cap terminating in the truck area (oem style tank), if a component is to fail, it is the cap & fill neck...placing ignitable vapors in the truck area......simply not smart.
Yes, with a real fuel cell this would be a managed risk, but with a oem style tank, no way.
I LIVE IN A FULL SERVICE STATE. They pump EVERYONE's gas.. (although with the classic cars, hot rods and motorcycles, they let you if you ask), but some are stubborn until I tell them that they need to run the pump at half speed and HOLD it in place or it will fall out and make a mess, then they let me... but you never know when you need to make it idiot proof, just in case.
it definitly needs to be a straight up neck so the nozzle doesnt fall out. on my trips through oregon they let me pump my own gas.
I bought a late '80s model filler neck, shortened it, modified the mounting bracket only slightly, then used two sheet metal screws to attach it to the back of the existing framwork around the filler neck. It was the same size as the rubber hose attaching the stock curved neck, so it fit in very nicely. Put the now-just-decorative hinged filler cap on the outside and everything looks and operates perfectly and I haven't had any spillage inside the trunk.

Pour 1/2 .oz of gas in your trunk and go for a drive. The fumes will make you hate your car. Not worth the trouble.
When I painted my '95 I removed the cup that catches spilled gas around the filler neck. When I re-installed it I didn't put sealer around it. My first fill up where the gas just puts a few drops in the cup was an eye opening experience to say the least. I promptly removed the cup and put some RTV back around it to seal the cup against the quarter panel.

IIRC pre 1968 the old VW Beetles fuel filler was inside the front trunk. How is one of those treated in jurisdictions where there appears to be a prohibition on such a design?
