I have a 92 F-250 with a 460 with dual tanks. Every time I try to put gas in the filler neck backs up a the gas bubbles out. I have removed both filler tubes to check for any blockage, every thing is clear, this happens with the truck running also. Even after letting the truck sit for a while, when I remove tha gas caps its like the tanks are under pressure because the gas still bubbles out from the filler tube. Any help would be greatly appreciated.

check your tank vents and make sure your return fuel lines arent plugged, also theres two filler neck hoses, one on the inside for bringing fuel to the tank and the big outer for releasing the air in the tank while you fill er up
