I have a 2016 Nissan KingCab 4x4 V6 with about 19k miles. A few weeks ago I went to fill the truck with gas (had about 1/8 tankful). I set the nozzle to automatic fill as I always do and started filling. After a few seconds and maybe a gallon of gas, I heard the gas coming up the fill tube and it backwashed heavily, all over the side of the truck. I adjusted the nozzle in the fill and started filling manually, but even at the slowest rate I could manage, it kept backwashing. It took me about ten minutes to gradually nurse about six gallons into it before I gave up. Since that time, I have only managed to completely fill the tank once, and that was after nursing it manually all the way. Now it's back to six or eight gallons at best. It makes no difference what pump or station I use, or how empty or full the tank is. I'm going nuts. I drive about 300 miles a week, and this is a major pain.
