⚠️ Safety & Precautions

• 🔥 Work outside or in a well-ventilated area; no smoking, sparks, or hot lights near fuel vapors.
• 🔌 Hybrid safety: Keep the car OFF and keep the key fob at least 15 ft away so it cannot go to READY.
• 🧯 Keep a Class B fire extinguisher nearby.
• 🔋 Disconnect the 12V battery negative terminal before opening the fuel system.
• ⛽ Fuel will spill when lines are opened—use rags and a drain pan; wipe up immediately.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear seat bottom

• Use a flat trim tool to release the front seat-bottom clips (one near each outboard seating position).
• Lift the seat bottom up and out of the car.
• Pull straight up; don’t pry hard.

Step 2: Open the fuel pump service cover

• Locate the service cover in the floor under the rear seat area.
• Remove the cover fasteners using a 10mm socket or Phillips screwdriver #2 (fastener type can vary).
• Lift the cover and set it aside.

Step 3: Clean the area (important)

• Use shop rags to wipe all dust and dirt off the top of the pump module and surrounding area.
• Dirt falling into the tank can cause injector/fuel system problems later.

Step 4: Disconnect the electrical connector

• Press the lock tab and unplug the pump/module connector by hand (use a flat trim tool gently if the tab is stubborn).

Step 5: Disconnect the fuel line(s)

• Place a drain pan and shop rags under the connection.
• Use needle-nose pliers to remove any safety clip/retainer (if equipped).
• Use a fuel line quick-disconnect tool set (specialty) to release the quick-connect fitting, then pull the line straight off.
• Cap/cover the open line end with a clean rag to keep dirt out.
• Expect a small fuel spill—stay calm.

Step 6: Remove the fuel pump lock ring

• Mark the lock ring and tank with a line using a Phillips screwdriver #2 (light scratch) so you can align it during reassembly.
• Use a brass drift punch (specialty) and small hammer to tap the lock ring counterclockwise to loosen it.
• Remove the lock ring and set it aside.
• Brass helps reduce spark risk.

Step 7: Lift out the fuel pump module

• Carefully lift the module straight up.
• Angle it as needed to clear the fuel level float arm without bending it.
• Let fuel drain into the tank, then set the module into the drain pan.

Step 8: Replace the tank seal/O-ring

• Remove the old seal from the tank opening by hand (use a flat trim tool gently if stuck).
• Install the new seal evenly into the groove. Make sure it is not twisted.

Step 9: Install the new pump/module

• Transfer any required parts from the old unit to the new one if your replacement didn’t include them (example: level sensor/float, depending on what you bought).
• Lower the new module into the tank, guiding the float arm carefully.
• Align the module’s index marks with the tank marks.

Step 10: Reinstall and tighten the lock ring

• Install the lock ring and tighten it clockwise using the brass drift punch (specialty) and small hammer until your alignment marks match.
• Torque to 68 Nm (50 ft-lbs) if using a lock-ring wrench tool; otherwise tighten firmly to the alignment marks without overstriking.

Step 11: Reconnect the fuel line(s) and electrical connector

• Push the fuel line straight on until it clicks/locks (use hands only).
• Reinstall any safety clip/retainer using needle-nose pliers.
• Plug in the electrical connector until it clicks.

Step 12: Reinstall the service cover and rear seat

• Reinstall the service cover using a 10mm socket or Phillips screwdriver #2.
• Reinstall the rear seat bottom: hook the rear edge first, then push down firmly at the front to snap the clips in.

Step 13: Reconnect the 12V battery

• Reconnect the negative terminal using a 10mm socket. Torque to 5 Nm (44 in-lbs).
• Tighten the gas cap.

✅ After Repair

• Cycle ignition to prime the system: press POWER to ON (not READY) for 5 seconds, then OFF. Repeat 3 times.
• Start the car and let it idle. Check for fuel smell and inspect the fuel line connection area for leaks.
• If you have a scan tool, check for pending codes and clear any fuel system-related codes after confirming no leaks.
• Test drive 10–15 minutes, then recheck for leaks again.
