🔧 Traverse - Fuel Pump Replacement

On your Traverse, the fuel pump is part of an in-tank fuel pump module. Replacing it can be a big job because many Traverses require lowering the fuel tank, but some vehicles have an interior access cover that makes it much easier.

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

⚠️ Safety & Precautions

• ⚠️ Work outside or in a very well-ventilated area—fuel vapors are explosive.
• ⚠️ No smoking, flames, heat guns, or shop lights that can spark near the vehicle.
• ⚠️ Depressurize the fuel system before disconnecting any fuel lines.
• ⚠️ Disconnect the negative battery cable to reduce spark risk.
• ⚠️ Support the fuel tank securely—never let it hang by hoses or wiring.
• ⚠️ Wear safety glasses and fuel-resistant gloves.

📋 Before You Begin

• 🧭 Park on level ground and set the parking brake.
• Run the fuel level as low as possible before starting. Less fuel = much easier.
• Open the fuel door and loosen the gas cap to relieve tank vapor pressure.
• Plan your approach: interior access cover (if equipped) vs lowering the tank.

🔨 Step-by-Step Instructions

Follow these steps in order:

Before I give the exact steps + the correct OEM torque specs for your Traverse, I need 2 quick checks (some builds differ):

• Look under the 2nd-row seat area or rear cargo floor for a round/oval metal access cover held by screws. Do you see an access panel, or is it solid floor?
• Are you replacing the pump because of a no-start/low-pressure issue, or because the gauge/sending unit is incorrect?

Reply with those two answers and I’ll give you the exact step-by-step for your setup (access-panel method or tank-drop method), including the correct tightening torques and line-disconnect points.

✅ After Repair

• Turn ignition ON for 5 seconds, then OFF for 10 seconds; repeat 3 times to prime fuel.
• Start the engine and inspect carefully for fuel leaks at every connection.
• Use an OBD2 scan tool to check for codes and verify fuel pressure (if available).
