2.875inch ID, Capless Gas Cap Dirt, Water & Dust Cover Compatible With 2015-2020 Ford and Lincoln Capless Gas Cap Fuel Filler Nozzle Cover

Thank

This is nothing more than a rubber cap, but it works. It fits perfectly on the gas intake to prevent unwanted air and debris getting in there. There is no gas cap just a door that often stays open. This cap does the job.

Works good to keep out dirt.A little hard to get off.

This expensive piece of plastic fits the truck. Unfortunately, it doesn't prevent 100% of the contaminants. The capless fuel check light still illuminates periodically. 3 stars for an average product that fits as advertised.

I hoped this was going to be the answer- but it didn’t do anything- obviously my evap problem is elsewhere

Works great on my truck

It will help keep dirt out of the fuel. It It made cheap but just pushes on.
