🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Fuel Door

• Wear the fuel-resistant nitrile gloves and ANSI Z87.1 safety glasses.
• Pull the fuel-door release lever located on the floor beside the driver’s seat.
• Open the released fuel door by hand.

Step 2: Remove the Old Fuel Cap

• Turn the old cap counterclockwise by hand until it comes off the filler neck.
• Let any brief pressure release finish before fully removing the cap.
• Inspect the filler-neck sealing surface for dirt, rust, or damage.

Step 3: Release the Cap Tether

• Locate the small tether anchor attached inside the fuel-door area.
• Use the small nylon trim-removal tool to gently release the tether anchor from its mounting hole.
• A trim-removal tool is a nonmetallic lever that releases plastic clips without scratching paint.
• Do not pull directly on the tether because it may break and leave the anchor behind.

Step 4: Install the New Tether

• Compare the new cap, sealing gasket, and tether with the removed cap.
• Press the new tether anchor into the original mounting hole by hand until it is fully seated.
• If needed, use the flat side of the small nylon trim-removal tool to press the anchor evenly.
• Confirm that the tether is not twisted or trapped by the fuel door.

Step 5: Install the New Fuel Cap

• Place the new cap squarely onto the filler neck by hand.
• Turn the cap clockwise until it clicks at least once. There is no numerical torque specification; the cap’s clicking mechanism controls tightening.
• Stop after a clear click.
• Close the fuel door and press it until it latches flush with the body.

✅ After Repair

• ✅ Make sure the fuel door opens, closes, and latches normally.
• 🔍 Check that the cap gasket sits evenly and the tether does not interfere with the cap.
• 🚗 If a loose-cap warning or check-engine light was already on, it may take several normal driving cycles to turn off after the leak test passes.
• ⚠️ If the light remains on, the evaporative-emissions system should be scanned for diagnostic trouble codes.
