If within the filler tube it may not be above the nozzle input OR it's blocked.
Options look down the filler tube and see if any blockage. If you cant see put a garden hose into tank and see if it goes into the tank ie measure it and blow in it to see if you can hear bubbles or air movement.
If this proves no blockage in filler you will need to see if the breather tube is blocked and to do this you could use a fine clear plastic hose - poke in and blow again (no bubbles here this time, but blow and see if you can hear where the air goes)
If you come across an obstruction you will soon know the problem
Otherwise suggest take it back (if new) OR get them to authorise repairs at their expense.

Why is it so? Professor Julius Sumner Miller, a profound influence on my life, who explained science to us on TV in the 60's.
I had a long-range fuel tank built and installed under the Sprinter. The inlet is a bit tricky and despite venting, the fuel spits out and stops the hand piece.
It cost me $3 the other day to come to that conclusion.
It was built and installed by Aussie By Design at Pt. Wakefield, and the problem has them puzzled. So at the moment I have a great tank of eair under the bus.
Has anyone got any clues about how I can get fuel into this tank.
A mate of mine suggested turning the nozzle to the "1 o'clock" position. I can only fit in the lo-flow nozzle but it just stops and spits back.

I have taken it back and they're still working on it. They installed a breather vent from the top of the tank to the filler. The rubber hose has a slight bend in it and the inbound fuel pushes back and shuts off the flow as if the tank is full.
I just thought someone out there in GN land might have a clue. I have suggested they install a sloped inlet rather than a straight in access to the tank to give a better downward flow.
Keep thinking folks.

HI CG. Mine does the same thing at most pumps. As your friend suggested, I have to 'turn' the pump nozzle to a couple of positions until fuel will flow normally (usually from the 9 to 3 o'clock range). Frequently I will still get some spit back and need to slow the amount to fuel going in. For some reason it is particularly bad at BP fuel pumps where I can only trickle feed the fuel which takes years to fill the tank. This is common to certain model twin cab rodeos and is apparently due the myriad of bends in the filler tube as it nears the fuel cap, a bit like multiple bends in sink waste plumbing causing small air locks. Of all people, an exhaust fitter suggested that by straightening out some of the bends, the problem should be rectified.
I have a late model Colorado and the same thing has been a problem for us.
Apparently it is common on Mazda BT 50' as well. Probably ford Ranger too, and there may be others.
After some serious investigation I found that the inlet filler pipe may have been too horizontal as well as having a restriction in the the outer top end of the metal filler pipe.
I removed the metal restriction to allow the pump nozzel to enter easily and the problem was solved.
There is now no blowback or stopping and the fuel goes in even from a fast flow pump.
I also may shift the filler pipe to a position just in front of the tray back behind the cab to increase the height and angle and improve access to the Fuel Cap.
I suspect that many of these parts are manufactured for use in a range of vehicles, particularly vehicles of Asian origin and the problem may be wide spread.
I was initially told by my dealer that the metal restriction was to prevent theft of fuel. Not so as two of my brothers siphoned 2 liters of diesel from my tank to burn a stump.
Some one will probably come up with a design rule to suggest I have done the wrong thing but my initial problem has been solved.
