📋 Before You Begin
- Park on level ground and set the parking brake.
- Make sure the fuel filler area is clean before removing the old cap.
- If the cap was loose, check the seal for cracks or hardening.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the old fuel cap
- Use your hand to turn the fuel cap counterclockwise until it releases from the filler neck.
- Lift the cap away from the opening and inspect the rubber seal.
Step 2: Install the new fuel cap
- Align the new fuel cap with the threads on the filler neck.
- Turn it clockwise by hand until it clicks or stops firmly.
- Do not over-tighten.
Step 3: Verify the seal
- Try turning the cap slightly after it seats; it should be snug and fully locked in place.
- Make sure the cap is flush and the tether, if equipped, is not pinched.
✅ After Repair
- Start the truck and make sure no fuel smell is present.
- If the check engine light was on, it may take a few drive cycles to clear after the system retests.
- Recheck the cap after your first fuel stop to confirm it is still tight.
