Blazer Fueling Problem

verlo1

WHEN I GO TO PUT GAS INTO THE TANK IT CLICKS OFF RIGHT AWAY. THER MUST BE A GAS TANK AIR VALVE SOME WHERE. WHERE IS IT AND HOW RO REPLACE IT. THANK YOU

It may simply be a problem with how you insert the nozzle into the gas tank receptacle. Be sure that the end of the nozzle does not make contact with the tube. Gas pumps have a cut-off mechanism that will activate when it senses a pressure change in the fuel flow. When the nozzle tip contacts the tube, the pressure drops and activates the cut-off.

Give that a try!

THIS IS NOT THE PROBLEM. IT IS SOMETHING IN THE EMISSIONS THAT WILL NOT RELEASE THE AIR OUT OF THE GAS TANK.

The emissions return specifically does not release air from the tank. You do have a canister mounted in the left rear quarterpanel, but that would not cause this problem. A damaged filler tube, or something in the filler tube itself could cause this, but there is no vent for filling the tank.

ps, please turn off the capslock. Makes it hard to read, and is computerese for shouting.

Then it's probably the vent valve located at the top of the gas tank. Perhaps someone with hands on experience would jump in to provide some guidance here?

did you find out what was causing this? My son's 2001 blazer is doing the same thing. He has to get gas in a gas can then put it in his blazer.
