    dont you all love the season where everything breaks thats what we had this year... but its the nature of the beast. we have a 2004 gmc 2500 and when filling up the tank it keeps making the pump shut off after about 2 to 4 gallons no matter how the nosle is placed and i can hear a whistling when its filling up like its not venting right anybody else have that problem and a solution to it....by the way its a 6.0 gasser but going from when the gas light is on till 1/4 tank it fills fine then after that it gose straight to hell.... :realmad::mechanic:
