My truck does the same thing when I fill up at certain stations, but not everywhere. I just don't go back to the gas stations where that happens. I think it has something to do with the angle of the end on the hose.

My truck does the same. only after i put my new tank in.
There is a vent hose in the filler neck, if this hose is bent, squeezed, or broke, then it will interupt the flow of gas, and or/ spew some back out at you. Some gas pumps compensate for the vent hose.
As for the gas guage not coming on, you either have a wire shorting out that connects to you sending unit, or the float is inoperative/sticking.
ya my ranger did the thing with the illing up it worked out of two stations around here. ive only tryed two stations with the f150 and those two are the ones the ranger worked with maybe i gotta try more stations.

installing a new rear tank isn't too much trouble, just connecting hoses and things of that sort, not very technical. Look on ebay (link below), rear tanks are usually pretty cheap and offer free shipping. Compare it with autozone and its usually at least 20 bux cheaper (plus the convenience factor and gas savings!) Don't forget to order tank straps, and a hose for the rear filler neck if its not still on the truck.
