Casey’s gas pumps accept the Hy-Vee Fuel Saver card for discounting the price of the gas. Hy-Vee sent out an updated black version of their Hy-Vee Fuel Saver card. Casey’s gas pumps did not know what to do with the black version of the Hy-Vee Fuel Saver card. It did process my red card version and applied that discount to the price of my gas purchase automatically. I strongly advise you hold on and carry the red card version as well as the new black version if you have received one. Casey’s automated gas pump worked as expected after the red Hy-Vee Fuel Saver card was inserted and pulled out.
