🔧 Fuel Pump - Replacement

The fuel pump on your Equinox is inside the fuel tank. This job usually means lowering the fuel tank, disconnecting the pump module, and installing a new module with a fresh seal. Fuel system pressure and gasoline fumes make this a careful, safety-first repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel system pressure

• Use the fuel pressure gauge or service procedure to relieve pressure from the fuel system.
• Wrap the connection with a shop towel before disconnecting anything.
• Keep your face away from the line.

Step 2: Disconnect the battery

• Use the 10mm socket to remove the negative battery cable.
• Move the cable aside so it cannot spring back and reconnect.

Step 3: Raise and support the vehicle

• Use the floor jack and jack stands to safely lift and support the Equinox.
• Place the jack stands at approved lift points.
• Make sure the vehicle is stable before crawling under it.

Step 4: Remove the fuel tank shield and related underbody parts

• Use the 10mm socket, 13mm socket, and trim clip removal tool to remove any shields or splash panels blocking the tank.
• Set all hardware aside in order.

Step 5: Disconnect the filler neck and tank connections

• Use the flat blade screwdriver and trim clip removal tool to loosen any hose retainers or shields around the filler neck.
• Disconnect the vapor lines and electrical connectors on top of the tank.
• Use the fuel line disconnect tool set for the quick-connect fuel and vapor fittings.
• Label each line if needed.

Step 6: Support and lower the fuel tank

• Use the floor jack with a wood block to support the fuel tank evenly.
• Remove the tank strap bolts with the 15mm socket.
• Lower the tank slowly and check for any missed connectors or hoses.

Step 7: Remove the fuel pump module

• Clean the top of the tank area so dirt cannot fall inside.
• Use the fuel pump lock ring tool (specialty) or a suitable lock-ring tool to remove the retaining ring.
• Lift the fuel pump module straight out of the tank.
• Remove the old seal and inspect the tank opening for damage.

Step 8: Install the new fuel pump module

• Install the new fuel pump seal / tank gasket in the correct groove.
• Lower the new fuel pump module into the tank carefully.
• Install the lock ring and tighten it to factory specification.
• Reconnect any internal hoses or clips exactly as removed.

Step 9: Reinstall the fuel tank

• Raise the tank with the floor jack and wood block.
• Reconnect all electrical connectors, vapor lines, and fuel lines.
• Use the 15mm socket to reinstall the tank straps.
• Tighten the strap bolts to factory specification.

Step 10: Reinstall shields and reconnect the battery

• Use the 10mm socket and 13mm socket to reinstall shields and brackets.
• Reconnect the negative battery cable with the 10mm socket.

Step 11: Prime and check for leaks

• Turn the key to ON for a few seconds, then OFF. Repeat 2-3 times to prime the system.
• Inspect the tank, lines, and module top for leaks.
• Start the engine and let it idle while checking again for fuel odor or wet spots.
