🔧 Versa - Fuel Pump Replacement

The fuel pump on your Versa is an in-tank module that supplies pressurized fuel to the engine. Replacement is usually done through an access panel under the rear seat, so you typically do not need to drop the fuel tank.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours

Assumption: Your Versa has a rear-seat access panel (most do); torque values can vary by fastener—verify if you have factory service data.

⚠️ Safety & Precautions

• ⚠️ Work outside or in a well-ventilated area—gas fumes ignite easily.
• ⚠️ No smoking, sparks, hot bulbs, or power tools near the opening.
• ⚠️ Disconnect the battery before opening the fuel system.
• ⚠️ Keep a fire extinguisher rated for flammable liquids nearby.
• ⚠️ Clean around the pump before removal—dirt in the tank can damage the new pump.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Open the fuel door to help reduce tank vapor pressure.
• Relieve fuel pressure before disconnecting lines.
• Disconnect the negative battery cable after pressure is relieved.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure

• Open the hood.
• Remove the fuel pump fuse/relay from the under-hood fuse box (IPDM). Use the trim panel removal tool to lift the fuse box cover.
• Start the engine and let it run until it stalls. Crank 2–3 more seconds to bleed off remaining pressure.
• Turn the key OFF.
• A “relay” is a plug-in electrical switch.

Step 2: Disconnect the battery

• Use a 10mm wrench to loosen the negative battery terminal and remove it.
• Tuck the cable aside so it cannot spring back to the battery post.
• Torque to 6 Nm (53 in-lbs) when reinstalling the terminal.

Step 3: Remove the rear seat bottom cushion

• From the rear footwell area, use the trim panel removal tool to pop the front edge of the seat cushion up from its clips.
• If your cushion has retaining bolts, remove them using a 10mm socket and 3/8" drive ratchet.
• Lift the cushion out and set it aside.
• Torque to 18 Nm (13 ft-lbs) for any seat cushion bolts on reassembly.

Step 4: Remove the fuel pump access cover

• Locate the round/oval metal access cover under the seat.
• Use a Phillips #2 screwdriver to remove the screws.
• Lift the cover off. Use the trim panel removal tool if it’s lightly stuck to sealant.
• Torque to 3 Nm (27 in-lbs) for access cover screws on reassembly.

Step 5: Clean the area and label lines

• Use shop towels to wipe dirt away from the top of the module.
• Use a permanent marker to mark the supply/return/vapor line positions (if more than one line).
• Cleanliness here prevents tank contamination.

Step 6: Disconnect the electrical connector

• Press the connector lock tab and unplug it by hand. If needed, gently assist with a small flat-blade screwdriver.
• Do not pull on the wires—pull on the connector body.

Step 7: Disconnect the fuel line(s)

• Place a small non-metal catch pan and shop towels under the connections.
• Use needle-nose pliers (if equipped with a clamp) or press the quick-connector tabs by hand to release the line.
• Cap/hold the line up to reduce spilling.

Step 8: Remove the lock ring

• Mark the lock ring and tank with a permanent marker so you can align it during installation.
• Use a fuel pump lock ring wrench (specialty) to turn the ring counterclockwise and remove it.
• A lock ring wrench grips the ring without sparks.

Step 9: Remove the fuel pump module

• Carefully lift the module straight up. Tilt it slightly as needed to clear the float arm (fuel level sensor arm).
• Let fuel drain back into the tank before fully removing it.
• Remove and discard the old fuel pump tank seal O-ring.

Step 10: Install the new seal and module

• Install the new fuel pump tank seal O-ring into the tank groove (not on the module).
• Lower the new module in, keeping the float arm from bending.
• Align the module’s locating marks/tabs to the tank (use your marker lines as a guide).

Step 11: Reinstall the lock ring

• Install the lock ring and tighten using the fuel pump lock ring wrench (specialty).
• Torque to 65 Nm (48 ft-lbs).
• Stop if the seal pinches or rolls.

Step 12: Reconnect lines and connector

• Reconnect fuel line(s) until you feel/hear a click; gently tug to confirm it’s locked.
• Reconnect the electrical connector until it clicks.

Step 13: Reinstall the access cover and rear seat

• Reinstall the access cover using the Phillips #2 screwdriver.
• Torque to 3 Nm (27 in-lbs).
• Reinstall the rear seat cushion (and bolts if equipped) using the 10mm socket and 3/8" drive ratchet.
• Torque to 18 Nm (13 ft-lbs).

Step 14: Restore power and prime the fuel system

• Reconnect the negative battery terminal using a 10mm wrench.
• Torque to 6 Nm (53 in-lbs).
• Reinstall the fuel pump fuse/relay and close the fuse box cover.
• Turn the key to ON (do not start) for 5 seconds, then OFF. Repeat 3 times to prime the system.

✅ After Repair

• Start the engine and let it idle for 1–2 minutes.
• Check carefully for leaks at the pump top and fuel line connection(s) under the rear seat.
• Take a short test drive, then recheck for fuel smell or dampness.
• If you have a check engine light afterward, a loose connector or an EVAP/vapor line not fully seated is the most common cause.
