1995 ford econoline
95 ford econoline van will not take gas... when i use the pump it clicks right off. when i use a can it fills to the top of the neck... is there anything at the gas tank in in the filler tube. i have pulled the filler tube to the rubber section and it is clear. did not check the air tube though just the gas. is there a valve on the air tube that maybe is not opening to vent out. or is there perhaps a security device to prevent siphoning on the filler side. when i tried to fill it with a can a heard a very distinct glug glug glug sound underneath as gas took turns with air entering the tank.
