🔧 Traverse - Fuel Pump Replacement
On your Traverse, the fuel pump is part of an in-tank fuel pump module. Replacing it usually requires safely depressurizing the fuel system and lowering the fuel tank (some vehicles have an access panel, but many do not).
Difficulty Level: Advanced | Estimated Time: 3-6 hours
⚠️ Safety & Precautions
- 🔥 Fuel vapors are extremely flammable—work outdoors or in a well-ventilated area.
- 🧯 Keep sparks/flames away (no smoking, no drop lights with hot bulbs).
- 🪫 Disconnect the negative battery cable before opening the fuel system.
- 🛑 Support the vehicle on jack stands—never rely on a jack alone.
- ⚠️ Relieve fuel pressure before disconnecting any fuel line to prevent spray.

đź“‹ Before You Begin
- Park on level ground, set the parking brake, and chock the front wheels.
- Run the fuel level as low as possible—dropping a full tank is much harder and less safe.
- Plan your work area so you can lower the tank straight down without dragging it.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Confirm the correct procedure path
- I need one detail to give you the exact factory-correct steps and torque specs: is your Traverse FWD or AWD?
- Second quick check: do you see an access panel under the rear seat/cargo carpet (a metal cover with screws), yes or no?
Step 2: Depressurize the fuel system (once you reply)
- After you answer the two questions above, I’ll lay out the exact depressurizing method and the correct disconnect points for your Traverse.
- Fuel spray is the #1 surprise here.
Step 3: Replace the pump module (once you reply)
- I’ll provide the correct tank-lowering/access steps for FWD vs AWD, the line routing, electrical connector handling, and the correct reassembly torque specs.
âś… After Repair
- Cycle the ignition to prime the system, then check carefully for leaks before starting.
- Verify the fuel gauge reads correctly and no fuel smell is present.
