Difficulty: Beginner · About 30 min · Gmc Sierra K1500

Replace the fuel door spring on a 1988–1999 GMC Sierra by removing the fuel door and transferring the spring into its retaining tabs.

Steps

1. Remove the fuel door

   Open the fuel door and remove its two T30 fasteners. Loosen the three nearby filler-neck fasteners enough to free the door assembly, then lift the door away.

2. Remove the old spring

   Use a flat screwdriver to carefully release the spring from the fuel door tabs. Note how its ends sit so the replacement can be oriented correctly.

3. Install the replacement spring

   Seat the new spring ends in the fuel door tabs, using a screwdriver to guide the tabs if necessary. Confirm the spring is retained and moves without binding.

4. Reinstall and check the door

   Position the fuel door and reinstall its two fasteners, then retighten the filler-neck fasteners. Open and close the door to confirm it springs and latches normally.

Check your vehicle’s repair manual for exact specifications and fit.
