Gas fill door

snowblind · July 31

My gas fill door does not stay closed. Not sure what happened, but it works its way to about a inch open every trip. Need a fix to this. 2020 Silverado 1500.

Common failure. You need to replace the fuel door housing.

The painted cover transfers over to the new housing. To remove the old one there is 4 spots where you poke the plastic to release it.
