NAPA Gas Caps "Junk"

[54blackhornet]

Had to let you all know that I am on my second NAPA has cap in less then a year. First one lasted about a year, took it back and showed the owner the rubber sealing ring was all cracked and falling apart. He gave me another one last month, it's already doing the same thing. I run non-ethanol fuel in my GMC because it sit's un driven during the winter. Any one know of a quality cap ? I was told STANT makes the NAPA cap.
