My F-150 had a fuel funnel for adding fuel from a gas can into the capless filler port on the truck. Ford had a special mounting location behind the rear seat and it was covered in the factory manual. With my 2025 Silverado the manual does not state where to find the fuel filler funnel in the truck. I phoned the dealer and was told that it should be in the glove box which it was not.

No help from Chevy roadside assistance and so I ordered a replacement from Amazon. This item should have been on the checklist for the dealer prep person but clearly was omitted.
