Unfamiliar with UrQ gas tank location, but Huw---does your Ford fill at the B-Pillar? If so, and it is similar in design to the old Chebbies, tossing the smoke out the window is not nearly as dangerous as getting the truck on its drivers side. BTST, recently finished dancing with MG over the design [In-cab fuel system, exposed filler spout]. Nasty design. Bruce
