"I live in the desert and wanted something to keep blowing sand and dust out of the capless filler neck. This fit the bill perfectly. The companion Def cap is a perfect replacement for the cheap plastic OEM one. The magnets make both caps easy to stick to the fuel door hinge while serving either Diesel or Def."
"Since I’m a first time diesel owner, I purchased these caps to slow me down at the pump to make sure I didn’t grab the wrong pump Green pump handle Green cap I will not put gas into my diesel because it’ll be very expensive slow as fast fast is wrong"
"They are tremendous. Since purchasing my Ram 2500 I was always concerned that while adding Def the nozzle might slip and have Def spill into the capless Diesel port. These caps have taken care of that. Plus, it helps those who may slip up and pour Def into the Diesel port with the capless system these caps add another safe guard for that. I also like the strong magnets on each cap for allowing you to attach them to the fuel door while adding either Def or Diesel. As always Excellent job Banks!! You think of everything."
