🔧 Fuel Pump Module - Replacement

This job involves lowering the fuel tank and replacing the in-tank fuel pump module. On your Equinox, the pump is inside the fuel tank, so you must relieve fuel pressure first and work carefully around fuel vapors.

Difficulty Level: Advanced | Estimated Time: 3-5 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve fuel pressure and disconnect battery

• Use the approved fuel pressure relief procedure, then disconnect the negative battery cable with a 10mm socket.
• Wait a few minutes after disconnecting the battery before opening fuel lines.

Step 2: Raise and support the vehicle

• Use a floor jack (rated 3-ton minimum) and support the Equinox securely on jack stands (rated for vehicle weight).
• Make sure the rear of the vehicle is high enough to lower the tank safely.

Step 3: Remove any tank shields or underbody covers

• Use an 8mm socket and 10mm socket to remove the fasteners holding the shield or cover.
• Set all hardware aside in order.

Step 4: Disconnect the filler and vent connections

• Use a flat-blade trim tool if needed to release retaining clips on the filler neck or splash shields.
• Mark hose positions with a marker or paint pen before removing anything.

Step 5: Support the fuel tank

• Place a floor jack (rated 3-ton minimum) with a fuel tank strap support block under the tank.
• Lift just enough to hold the tank steady.

Step 6: Remove the fuel tank straps

• Use a 13mm socket and ratchet to remove the strap bolts.
• Lower the tank slowly and check for any remaining wiring or hoses.
• Torque on installation: Torque to 25 Nm (18 ft-lbs) for the strap bolts.

Step 7: Disconnect fuel lines and electrical connector

• Use the fuel line disconnect tool to release the fuel supply line.
• Unplug the electrical connector from the pump module.
• Use shop towels to catch any spilled fuel.

Step 8: Remove the fuel pump module

• Clean the top of the tank area before opening it.
• Remove the locking ring by hand if possible; if it is tight, use a suitable non-sparking tool.
• Lift the fuel pump module straight out of the tank carefully.
• Do not bend the float arm.

Step 9: Install the new module and seal

• Install the new fuel pump module seal in the tank opening.
• Lower the new fuel pump module into place in the same orientation as the old one.
• Install and lock the retaining ring fully.

Step 10: Reconnect lines, raise tank, and reinstall straps

• Use the fuel line disconnect tool to reconnect the fuel line until it clicks.
• Reconnect the electrical connector.
• Raise the tank with the floor jack (rated 3-ton minimum).
• Install the straps using the 13mm socket.
• Torque to 25 Nm (18 ft-lbs) on the strap bolts.

Step 11: Reinstall shields and reconnect battery

• Reinstall any covers or shields with the 8mm socket and 10mm socket.
• Reconnect the negative battery cable with the 10mm socket.

Step 12: Prime and check for leaks

• Turn the key to ON for 5 seconds, then OFF. Repeat 3 times to prime the system.
• Start the engine and inspect all connections for leaks.
• Check for fuel odor around the tank and filler area.
