Fuel Pump for 2012 Chevy Cruze: The Complete Guide to Replacement and Choosing the Right Part

The bottom line: If you own a 2012 Chevrolet Cruze and your fuel pump is failing, you need to replace the fuel pump module assembly—a complete unit that sits inside the fuel tank, accessed under the rear seat. The job is doable as a DIY project in about 1.5 to 3 hours, but you must choose the correct part for your engine size (1.4L turbo or 1.8L naturally aspirated) and follow proper safety procedures when working with gasoline. OEM parts from GM or high-quality aftermarket replacements like KEMSO are your best options for reliability.

Signs Your 2012 Chevy Cruze Fuel Pump Is Failing

Before you buy a replacement, it helps to know what symptoms point to a bad fuel pump. On a 2012 Cruze, the fuel pump is part of an in-tank “fuel pump module” that sits under the rear seat . Common signs of failure include:

1. Engine cranks but won’t start – This is the most obvious symptom. You hear the starter turning the engine over, but it never fires up. The pump may have stopped delivering fuel to the injectors.

2. Sudden loss of power while driving – The car may sputter, hesitate, or lose power, especially under load or going uphill. This happens when the pump can’t maintain consistent fuel pressure.

3. High-pitched whining noise from the rear of the car – A healthy fuel pump runs quietly. If you hear a loud whining or humming sound coming from under the rear seat area, the pump is likely wearing out .

4. Low fuel pressure – If you have a fuel pressure gauge, a reading below specification (usually around 55-60 psi for the 1.4L turbo) indicates a failing pump.

5. Check Engine Light – In some cases, the car’s computer will detect low fuel pressure or a lean fuel mixture and trigger the check engine light with codes like P0087 (Fuel Rail/System Pressure Too Low).

Which Fuel Pump Fits a 2012 Chevy Cruze?

The 2012 Chevy Cruze came with two main engine options, and each uses a different fuel pump module. Getting the wrong part will not fit, so double-check your engine size before ordering.

For the 1.4L Turbo Engine (common in LT and LTZ trims): The OEM part number is 13510673 . This pump module fits the 2011-2016 Cruze with the 1.4L turbo and a 13-gallon tank. It does not include a fuel level sensor, so you may need to transfer the sensor from your old pump. Other compatible part numbers include 13580532 (replaces the original) and 42706338 for later model years .

For the 1.8L Naturally Aspirated Engine (common in LS trims): The OEM part number is 13503672 or 13251237 . Aftermarket options like the Herko 901GE also fit this engine, covering 2011-2014 model years . The 1.8L pump module is different from the 1.4L version, so make sure you select the correct one.

Universal aftermarket options: Many aftermarket brands offer a direct replacement for the 2012 Cruze that includes both the pump and sending unit. The LUJUNTEC Electric Fuel Pump Assembly fits 2011-2015 Chevy Cruze with both 1.4L and 1.8L engines . The AJD Fuel Pump Assembly (model F01R00S296) is another option suited for 2009-2012 model years with 1.6L, 1.8L, and 2.0L engines .

How to Replace the Fuel Pump on a 2012 Chevy Cruze

The replacement process is considered intermediate difficulty. Plan for 1.5 to 3 hours of work, and make sure you have a clean, well-ventilated workspace .

Tools you’ll need:

  • 10mm socket and 1/4" drive ratchet
  • Trim removal tool
  • Flat-blade screwdriver
  • Fuel line quick-disconnect tool set
  • Fuel pump lock ring tool (or a brass punch and hammer)
  • Needle-nose pliers
  • Shop towels and a shallow catch pan
  • Safety glasses and nitrile gloves

Parts you’ll need:

  • New fuel pump module assembly (correct for your engine)
  • New fuel pump module tank seal (O-ring/gasket)
  • Replacement fuel line retainer clips (if needed)

Step-by-step instructions:

1. Relieve fuel pressure first. Open the hood and remove the fuel pump fuse or relay from the underhood fuse box. Start the engine and let it run until it stalls. This releases the pressure in the fuel lines so you don’t get sprayed with gasoline when disconnecting them .

2. Disconnect the negative battery cable. Use a 10mm socket to remove the cable from the battery terminal. This reduces the risk of sparks while working around fuel.

3. Access the fuel pump module. The fuel pump is located under the rear seat. Remove the rear seat cushion by pulling up on the front edge. You’ll see a metal access cover on the floor pan. Remove the screws or bolts holding the cover in place.

4. Disconnect the electrical connector and fuel lines. Use the fuel line quick-disconnect tool to release the fuel supply line and return line (if equipped). Be ready for a small amount of fuel to spill—have shop towels and a catch pan ready.

5. Remove the lock ring. The fuel pump module is held in place by a large plastic or metal lock ring. Use a fuel pump lock ring tool or a brass punch and hammer to tap the ring counterclockwise until it loosens. Do not use a steel punch or hammer directly on the ring—this can create sparks.

6. Lift out the old module. Carefully lift the old pump module out of the tank. Note how the fuel level sensor arm and float are positioned so you can install the new one correctly. Place the old module in a catch pan to drain any remaining fuel.

7. Transfer the fuel level sensor if needed. Some replacement pump modules do not include a new fuel level sensor. If your new pump doesn’t have one, remove the sensor from the old module and install it on the new one.

8. Install the new pump module. Place the new O-ring seal into the groove on the tank opening. Lower the new pump module into the tank, making sure the float arm moves freely and doesn’t hit the sides of the tank. Press the module down until it seats fully.

9. Install the lock ring. Place the lock ring over the module and tighten it clockwise using the lock ring tool. Tighten it securely, but don’t overtighten—the ring should be snug, not forced.

10. Reconnect everything. Reconnect the fuel lines (push them on until you hear a click), plug in the electrical connector, and replace the access cover. Reinstall the rear seat cushion.

11. Reinstall the fuel pump fuse or relay. Put the fuel pump fuse or relay back in the underhood fuse box.

12. Prime the fuel system. Turn the key to the “ON” position (without starting the engine) for 2-3 seconds, then turn it off. Repeat this 2-3 times to allow the fuel pump to build pressure. Then start the engine and check for leaks.

Safety Tips for Fuel Pump Replacement

Working with gasoline is dangerous. Follow these rules to stay safe:

  • Work outside or in a well-ventilated area. Gasoline fumes are highly flammable and can accumulate in enclosed spaces .
  • No smoking, flames, or hot work lights. Keep any source of ignition far away from your workspace.
  • Keep a fire extinguisher nearby. A small Class B (flammable liquids) fire extinguisher is a good investment.
  • Wear safety glasses and nitrile gloves. Gasoline can irritate your skin and eyes.
  • Clean the area around the fuel pump access cover before opening it. Dirt and debris falling into the fuel tank can clog the pump or injectors.

Genuine GM vs. Aftermarket Fuel Pumps: Which Should You Choose?

When it comes to fuel pumps, you have three main options: genuine GM parts, name-brand aftermarket parts, and budget aftermarket parts.

Genuine GM parts are the most expensive but offer guaranteed fitment and factory warranty coverage. The GM part number 13510673 for the 1.4L engine typically costs around $215-$253 depending on the seller . These parts are designed, engineered, and tested to rigorous standards by General Motors. If you want the peace of mind that comes with an OEM part, this is the way to go.

Name-brand aftermarket parts from companies like Herko, Bosch, and DeatschWerks offer good quality at a lower price point. The Herko 606GE fits the 2010-2013 Cruze with 1.4L and 1.8L engines . The DeatschWerks 340lph compact fuel pump is a high-performance upgrade that fits 2011-2016 Cruze models and is popular among enthusiasts who want higher flow capacity .

Budget aftermarket parts from lesser-known brands can save you money upfront, but they often come with shorter warranties and may not last as long. If you’re on a tight budget, look for brands that offer at least a 1-year warranty and have positive customer reviews.
