“On 3 occasions pumping gas in the last 4 months I have had problems with gasoline spewing out of the tank after I remove the pump nozzle. It was not a simple failure of the pump to turn off. It seemed like air pressure built up much like pumping up an air canister to spray weed killer on a yard. The gasoline covered my arm and sprayed onto the pump. Each occasion was at a different station and all of the stations were relatively new. It does not happen at our regular service station.”
