As we passed through Claude Tx we noticed the bus cutting out and acting like it had a fuel issue. There were no auto stores so we kept going to Amarillo. It was a slow drive, we couldnt give it to much gas. By this time we figured we were in need of a new fuel pump. We were traveling with an extra electronic pump but we hoped to make it to an auto store to get the mechanical one. We made it and found when we opened tthe tool box a spare mechanical one... oops, 2 spares are better than 1. So far we are making it fine in the heat, the dogs seem good. We are now in Amarillo eating lunch.
