It's obviously another way for ford to make money off you. Please buy our special funnel. I will say I had an explorer as a rental car about a year back and after I pumped the gas I stood there for three or four minutes wondering to myself if I took the cap off or not, I think it's weird how these new cars don't have the traditional screw caps.
