Open your fuel door and remove the two T30 Torx screws securing it to the bed of the truck. Loosen the other three T30 Torx screws around the filler neck. Once the screws are loose you should be able to work the back side of the fuel door around the rubber.

Once the fuel door is removed, use a flat blade screwdriver to pry the spring out of it's hook and then pop it up out of its tabs in the rear here. Slide the spring out of the assembly.

Here we have our old spring and our new part from 1AAuto.com. You can see that the shape is exactly the same, so it's going to fit right in there and make everything move nice. The other thing is you can see we have a coated steel here, which is going to be a lot stronger and more resistant to rust, meaning it will last longer and do what we want it to do. So if your old fuel door spring is broken, rusted out or failed, this new part from 1A Auto will go and direct fit just like our original equipment and fix you up right.

Slide your spring back into the assembly, work it around back into place and back into their slots in the fuel door. You may need your screwdriver to help pry it out here. Once those are in place, push down. This takes a little bit of force so watch yourself, keep your hands out of the way in case the screwdriver slips, you don't want to hurt yourself. Reinstall the fuel door. Line up your two T30 Torx bolts and reinstall them. Tighten up the other T30s you loosened and you're good to go.
