🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fuel door

• Press the fuel door in to release it (your Atlas uses a push-to-open door when unlocked).
• If it won’t open, use the key fob to unlock the doors and try again.

Step 2: Remove the old fuel cap

• Use nitrile gloves and turn the cap counterclockwise until it releases.
• Let the tether hang so the cap doesn’t scratch the paint. The tether is the small strap that keeps the cap attached to the vehicle.

Step 3: Inspect and wipe the sealing surface

• Use a flashlight to look at the filler neck opening.
• Use a clean shop towel to wipe dirt or grit off the sealing lip so the new cap can seal.

Step 4: Install the new fuel cap

• Thread the new cap on by hand, turning clockwise.
• Tighten until you feel/hear it fully seat (a secure “ratcheting/click” feel is normal on many OEM-style caps).
• Hand-tight only—no tools.

Step 5: Close the fuel door

• Push the fuel door closed until it clicks shut.
• Use a clean shop towel to wipe any fingerprints or fuel residue.

✅ After Repair

• Start the engine and confirm there is no fuel smell around the filler area.
• If your check-engine light was on for a loose cap, it may take a few drive cycles to turn off on its own.
• If the light stays on after a few days, you may need a scan for stored codes (common related code is an EVAP leak).
