The stant parts number for the gas cap is 10838, just incase you need it, like i did. Had to buy a new gas cap today, lost the original one somewhere, gas station didnt have it. Is there any reason why jeep didnt include a peice to anchor the gas cap to the fill hole? Anything we can do about this? I dont want to lose another one :P Would a small peice of steel cable work here? Any other ideas?
