Can't fill my gas tank on a 2010 F150
Lately, when I fill up my truck my fuel gauge never reads 'F' even though I fill the tank to the point where I cannot even top off the fuel. The gauge reads to be about 98-99% full, just short of 'full'. In fact, I pumped 27.3 gallons in the tank and tried to pump a little more, but it wouldn't take. The truck is new with 3900 miles. I do have a gas locking cap on the tank and I am not sure if this has any affect.
Any ideas what may cause this?
My thanks.

Sounds to me like the wiper is maybe not tensioned sufficiently to make perfect contact on the windings of the resistor strip (sending unit in tank) up near the top or "short" end of the windings.
I have had a couple cars over the last 40 years that had a simular problem. One had a dip in center swing so that it read full, but after a few dozen miles, gauge dropped below half and stayed there until you used up the gas to catch up, then it worked OK if one didn't gas up. It just started one day. On another, it developed an intermittent problem working good at times, and not so good others. Then on my '85 GoldWing, it stopped reading above 3/4 tank once.
In all three cases, problem resolved by removing sending unit from tank and taking a pair of small needle nose pliars and just very carefully and slightly, and with care, "tweak" the arm that wipes the resistor strip to add pressure, just a hair .... and I usually gave the resistor strip a shot with 2+2 Gum Cutter to clean off any possible contaminates.
Worked for me everytime so far! Do not "overtweak" the arm as too much pressure might cause excessive wear on the windings .... or wiper shoe. It never stops moving with sloshing fuel as the vehicle is moving .... though in so many years with many well over 100,000 miles, even 150K, never saw one "wore out".
Had one other vehicle once though that just had a loose clip on a shaft. Easy fix there too.

Do this only in a well ventalated area clear of any flames or sparks or ignition sorces, no smoking allowed!
In your case, hardest part is going to be persuading a dealership to drop the tank and do it under warranty.
You might take a full 2010 (chances of finding such are virtually nill though) off the lot and top it off and show the dealer the difference .... if it is different.
