🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Fuel Door

• Use your hand to press the rear edge of the fuel door, then swing it open.
• Use a clean shop rag to wipe dirt from around the fuel filler area before removing the cap.
• Keep dirt out of the filler neck.

Step 2: Remove the Old Fuel Cap

• Use your hand to turn the fuel cap counterclockwise until it comes loose.
• Let the cap hang by the tether, or hold it carefully so it does not touch dirty surfaces.
• No torque spec is used here because the fuel cap is hand-tightened only.

Step 3: Release the Fuel Cap Tether

• Look at where the plastic tether attaches near the fuel door area.
• If the tether is clipped into a small hole or slot, use a small flathead screwdriver to gently pry the tether retainer loose.
• A retainer is a small plastic clip that holds the tether in place.
• Be gentle so you do not crack the plastic fuel door area.

Step 4: Compare the New Fuel Cap

• Use your hands to compare the old and new fuel caps side by side.
• Make sure the new cap has the same thread style, sealing gasket, and tether arrangement.
• The sealing gasket is the rubber ring that keeps fuel vapors from escaping.

Step 5: Install the New Tether

• Use your hand to push the new fuel cap tether retainer into the original hole or slot.
• If needed, use the small flathead screwdriver only to guide the clip into place.
• Do not force it. The clip should seat firmly without bending.

Step 6: Install the New Fuel Cap

• Place the new fuel cap onto the filler neck by hand.
• Turn the cap clockwise until it clicks.
• Honda-style caps should be tightened until you hear multiple clicks.
• Torque to hand-tight only until the cap clicks
• Clicks mean the seal is seated.

Step 7: Close the Fuel Door

• Use your hand to close the fuel door until it sits flush with the body.
• Wipe the area with a clean shop rag if you touched any fuel residue.

✅ After Repair

• ✅ Start your CR-V and check that the fuel door sits closed properly.
• 🧭 If a “Check Fuel Cap” message was present, drive normally for a few trips. It may clear after the vehicle runs its self-checks.
• 🔍 If the check engine light stays on after several drive cycles, the code may need to be cleared with a scan tool or there may be another EVAP system leak.
• ⛽ At your next fuel stop, reinstall the cap until it clicks every time.
