🔧 Equinox - Fuel Pump Replacement

On your Equinox, the fuel pump is part of an in-tank fuel pump module (pump + level sender). Replacement usually requires safely lowering the fuel tank, swapping the module, then reinstalling everything and checking for leaks.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

⚠️ Safety & Precautions

• 🔥 Work outside or in a very well-ventilated area; gasoline fumes ignite easily.
• 🧯 Keep a fire extinguisher rated for flammable liquids nearby.
• ⚡ Disconnect the negative battery cable before opening the fuel system.
• 🚫 Do not smoke or use heat guns/torches near the vehicle.
• 🛑 Relieve fuel pressure before disconnecting any fuel lines to avoid spray.
• 🧰 Support the fuel tank with a transmission jack or a floor jack and a wide wood block; never let it hang by hoses/wiring.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the front wheels.
• Get the fuel level as low as possible (ideally under 1/4 tank). Less fuel = a lighter, safer tank.
• Relieve fuel pressure: remove the fuel pump fuse/relay, start the engine, and let it stall; crank 3 seconds more, then key OFF.
• Disconnect the negative battery cable using a 10mm socket.
• Know your drivetrain path:
  • FWD: tank drop is more straightforward.
  • AWD: you may need extra clearance around the rear driveline/exhaust routing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Make the vehicle safe to work under

• Use a floor jack (rated 3-ton minimum) to lift the rear at the approved jack points.
• Set the vehicle onto jack stands (rated 3-ton minimum) and confirm it is stable before crawling underneath.

Step 2: Relieve fuel pressure (double-check)

• If you didn’t already, pull the fuel pump fuse/relay, then start the engine until it stalls.
• Turn key OFF and reinstall the fuse/relay after pressure is relieved.
• Fuel spray is the #1 DIY mistake here.

Step 3: Support the fuel tank

• Position a transmission jack (recommended) under the fuel tank.
• If using a floor jack, place a wide wood block on the jack pad to spread the load.

Step 4: Disconnect the EVAP and fuel lines at the tank

• Use shop rags and a drain pan to catch residual fuel.
• Disconnect the fuel feed/return quick-connects using a fuel line quick-disconnect tool set (specialty) (this tool slips into the connector to release the internal spring).
• Disconnect EVAP vapor lines using a trim clip removal tool or flat-blade screwdriver as needed (avoid snapping plastic fittings).
• Unplug the fuel pump electrical connector using a flat-blade screwdriver to release the lock tab if needed.

Step 5: Remove the filler neck and vent connections

• Loosen hose clamps using hose clamp pliers (or flat-blade screwdriver depending on clamp style).
• Twist the hoses gently to break them free; do not pry hard on the tank nipples.
• Mark hose positions with a permanent marker so they go back to the same spots.

Step 6: Lower the tank straps and drop the tank slightly

• Use a socket set 13mm-15mm (varies by fastener) and ratchet 1/2" to remove the fuel tank strap bolts.
• Lower the tank slowly with the transmission jack (recommended) while watching for any remaining hoses/wiring.
• If something stretches, stop and disconnect it before lowering further.

Step 7: Clean the area around the fuel pump module

• Use shop rags to wipe dirt off the top of the tank around the pump module.
• Keeping dirt out prevents repeat pump failure.

Step 8: Remove the fuel pump lock ring

• Use a brass drift punch (specialty) and small hammer to tap the lock ring counterclockwise.
• Lift the lock ring off and set it aside.
• Carefully lift the fuel pump module out; angle it to clear the float arm without bending it.

Step 9: Install the new pump module and seal

• Remove the old tank seal and install the new fuel pump module tank seal (O-ring) by hand.
• Insert the new module in the same orientation as the old one (match alignment marks).
• Reinstall the lock ring and tighten.
• Torque to 80 Nm (59 ft-lbs) if using a lock-ring tool; if tapping with a punch, tighten until the ring aligns fully with the stop marks.

Step 10: Raise the tank and reinstall straps

• Raise the tank into position using the transmission jack (recommended).
• Start strap bolts by hand to avoid cross-threading, then tighten with a socket set and ratchet.
• Torque to 25 Nm (18 ft-lbs) for tank strap bolts.

Step 11: Reconnect filler/vent hoses, EVAP lines, fuel lines, and wiring

• Reconnect hoses and tighten clamps using hose clamp pliers or flat-blade screwdriver.
• Reconnect fuel quick-connects by pushing until they click; then pull back gently to confirm they’re locked.
• Install any new fuel line retainer clips if the originals are loose or damaged.
• Reconnect the electrical connector until the lock clicks.

Step 12: Reconnect battery and prime the system

• Reconnect the negative battery cable using a 10mm socket.
• Turn key to ON (engine OFF) for 5 seconds, then OFF for 5 seconds; repeat 3 times to prime the fuel system.

✅ After Repair

• Start the engine and let it idle while you inspect underneath for leaks at every connection.
• If you smell fuel, shut the engine off immediately and re-check the quick-connect fittings and lock tabs.
• Test drive 5-10 minutes, then re-check for seepage again.
• If the check engine light comes on, scan for codes (EVAP codes are common if a vapor line isn’t fully seated).
