2006 Saturn Vue Fuel Pump Location: Where It Is and How to Access It

If you own a 2006 Saturn Vue and you are dealing with starting issues, stalling, or a fuel gauge that reads incorrectly, the fuel pump is likely the culprit. The fuel pump on a 2006 Saturn Vue is located inside the fuel tank, which sits under the rear of the vehicle. Unlike some cars, there is no access panel under the rear seat, so the fuel tank itself must be lowered or removed to reach the pump. This makes the job labor-intensive, but understanding exactly where the pump lives and how the system works will save you time and money when diagnosing the problem.

The 2006 Saturn Vue uses a saddle-style fuel tank that straddles the exhaust and driveshaft. Because of this design, the tank has two separate low spots, and the fuel system uses two modules to draw fuel from both sides. The primary fuel pump is on the passenger side, and a secondary unit sits on the driver's side. For the 2006 model year, there was a mid-production change, so you must check your Vehicle Identification Number (VIN) to determine which pump design your Vue has before ordering a replacement part.

The Short Answer: Where the Fuel Pump Is Located

The fuel pump assembly on a 2006 Saturn Vue is located inside the fuel tank at the rear of the vehicle. More specifically:

  1. Primary Fuel Pump (Passenger Side): This is the main electric pump that pressurizes fuel and sends it to the engine. It is mounted inside the fuel tank on the right-hand side of the vehicle.

  2. Secondary Fuel Transfer Unit (Driver Side): On the 2004-2007 models, this unit does not contain an electric motor. Instead, it uses a suction jet system powered by the primary pump's pressure to draw fuel from the left side of the tank. It also houses a fuel level sending unit.

  3. No Access Panel: There is no access hatch under the rear seat or trunk floor. To reach either unit, the entire fuel tank must be dropped from the underbody of the car.

Understanding the 2006 Saturn Vue Fuel System

The 2006 Saturn Vue is part of the second-generation fuel system design that GM introduced in 2004. This system is a returnless, on-demand design, meaning the fuel pressure regulator is built into the primary fuel tank module and there is no return fuel line running to the engine.

The system works like this:

  • The primary fuel tank module on the passenger side contains the electric turbine-style fuel pump, the fuel pressure regulator, the fuel filter, and a fuel level sensor.
  • The secondary fuel tank module on the driver's side contains a fuel level sensor and a passive pickup. It does not have its own electric pump.
  • A secondary jet pump inside the primary module creates a venturi action that draws fuel from the driver's side of the tank through a transfer pipe over to the passenger side.

This design is necessary because the saddle-style tank creates two separate reservoirs. Without the jet pump system, fuel on the driver's side would never reach the primary pump, and you would run out of gas with half a tank still showing on the gauge.

Critical VIN Check for 2006 Models

For the 2006 model year, there was a mid-production change to the fuel pump system. You must verify your VIN before ordering any fuel pump parts:

  1. 1st Design: Vehicles built before VIN 6S823055 use the first design pump.
  2. 2nd Design: Vehicles built on or after VIN 6S823055 use the second design pump.

These two designs are not interchangeable. If you order the wrong one, it will not fit correctly, and you will have to go through the entire removal process again. The VIN is located on the driver's side dashboard near the windshield, and also on a sticker in the driver's door jamb.

Symptoms of a Failing Fuel Pump in Your 2006 Vue

Before you drop the tank, it pays to confirm that the fuel pump is actually the problem. These are the most common signs of a failing fuel pump in a 2006 Saturn Vue:

  1. Engine cranks but will not start: If the pump is dead, no fuel reaches the injectors, so the engine will crank but never fire up.
  2. Sputtering or hesitation during acceleration: A weak pump cannot maintain the 50-60 PSI of fuel pressure the engine needs under load.
  3. Stalling at low fuel levels: This is a classic sign that the secondary jet pump has failed. When the fuel level drops below half a tank, the driver's side reservoir stays full, but no fuel transfers to the primary side.
  4. Fuel gauge reads incorrectly: The fuel level sending units are part of both tank modules. If the gauge is erratic or stuck, one of the sending units may be bad.
  5. Loud whining noise from the rear of the vehicle: A fuel pump that is wearing out often makes a high-pitched whine, especially when the tank is low.

A fuel pressure test is the most definitive way to diagnose the pump. A healthy system will show steady pressure, while a failed pump will show little to no movement.

Accessing the Fuel Pump: Step-by-Step Overview

Replacing the fuel pump on a 2006 Saturn Vue is an advanced DIY job. The fuel tank must be lowered from the vehicle, and there are several safety precautions to keep in mind. Here is a general overview of the process:

Step 1: Safety first
Disconnect the negative battery terminal and relieve the fuel system pressure. You can relieve pressure by removing the fuel pump fuse and cranking the engine until it stalls, or by using the Schrader valve on the fuel rail.

Step 2: Raise and support the vehicle
Use a floor jack and jack stands to safely raise the rear of the vehicle. Never work under a car supported only by a jack.

Step 3: Remove the exhaust and driveshaft components
You will need to remove the rubber exhaust hangers to allow the exhaust system to drop slightly. If your Vue is all-wheel drive, you may also need to remove the propeller shaft guard and the shaft itself.

Step 4: Disconnect fuel lines and electrical connectors
Clean all fuel pipe connections before disconnecting them to avoid contamination. Use fuel line disconnect tools to detach the fuel feed line from the fuel filter. Disconnect the fuel tank ground strap and the electrical connector for the fuel pump.

Step 5: Drop the fuel tank
Support the fuel tank with a jack, then remove the two metal tank strap bolts. Lower the tank carefully. Keep in mind that even a low fuel tank is heavy and awkward to handle.

Step 6: Remove the fuel pump module
Once the tank is down, you can see the fuel pump module on top of the tank. Remove the locking ring with the correct tool (often SA9156E), then lift the pump assembly out. Discard the old seal and inspect the tank for debris or rust before installing the new pump.

Step 7: Reinstall everything
Install the new pump with a new seal and locking ring. Reconnect all fuel lines, electrical connectors, and the fuel tank. Lower the vehicle and reconnect the battery.

Step 8: Prime the system
Turn the ignition key to the "ON" position for a few seconds, then off, and repeat several times before cranking the engine. This primes the fuel system and prevents long cranking times. Start the engine and check for leaks.

What About the Fuel Filter?

When you drop the tank to replace the fuel pump, you should know that the fuel filter is also located inside the fuel tank. On the 2006 Saturn Vue, the fuel filter is part of the primary fuel tank module and is not serviceable separately. You cannot replace just the filter without replacing the entire pump module. This is worth considering because a clogged filter can cause symptoms similar to a failing pump, and replacing the whole module at once solves both issues.

How Much Does a Replacement Cost?

Replacing the fuel pump on a 2006 Saturn Vue is not cheap, mostly because of the labor involved. The fuel tank must be dropped, which is a time-consuming job. Here are the estimated costs:

  • Total replacement cost: $1,847 to $2,594 for a 2006 Saturn Vue with the 2.2L engine.
  • Total replacement cost: $2,453 to $2,923 according to another estimate for the 2006 model year.
  • Part cost alone: Aftermarket fuel pump modules range from $82 to $529 depending on the brand and whether you need the primary or secondary unit.
  • Labor cost: Expect to pay $277 to $407 for shop labor.

These costs vary significantly based on your location, whether you have a 2.2L four-cylinder or a 3.5L V6, and whether the vehicle is front-wheel drive or all-wheel drive.
