2009 Dodge Ram 1500 5.7 Hemi Fuel Pump: Complete Replacement Guide

The bottom line up front: If you drive a 2009 Dodge Ram 1500 with the 5.7L Hemi V8 and you're dealing with hard starts, sputtering at highway speeds, or a truck that cranks but won't fire, the fuel pump is very likely the culprit. The fuel pump on this truck lives inside the fuel tank, and replacing the complete fuel pump module assembly is the smartest way to fix the problem. Expect to pay between $985 and $1,330 for a professional replacement, or around $160 to $330 in parts if you tackle the job yourself. A quality replacement module from a trusted brand like Delphi, Airtex, or KEMSO will restore reliable fuel delivery and get your Hemi running like it should again.

Why the 2009 Dodge Ram 1500 5.7 Hemi Fuel Pump Fails

The fuel pump in your 2009 Ram 1500 is an electric pump mounted inside the fuel tank. It is designed to last a long time, but several factors can shorten its lifespan.

Common reasons for premature failure include:

  1. Running low on fuel regularly – The pump uses the fuel in the tank to stay cool. Running the tank below a quarter full causes the pump to overheat and wear out faster.
  2. Contaminated fuel – Dirt, rust, and debris in the tank can clog the strainer and force the pump to work harder than it should.
  3. Age and mileage – By 2026, a 2009 truck has likely seen over 150,000 miles. The electric motor brushes and bearings simply wear out over time.
  4. Electrical issues – A failing fuel pump relay or wiring problem can cause voltage drops that damage the pump motor.

The 2009 Ram 1500 with the 5.7L Hemi uses a fuel pump module assembly that includes the pump, fuel level sending unit, float arm, and strainer all in one unit. This modular design makes replacement straightforward.

Warning Signs Your Fuel Pump Is Going Bad

Catching a failing fuel pump early saves you from being stranded on the side of the road. Here are the telltale symptoms to watch for:

  1. Engine sputtering or choking – The truck struggles to maintain speed, especially under load or going uphill.
  2. Difficulty starting – You have to crank the engine longer than usual before it fires up. The engine may also stall shortly after starting.
  3. Loss of power – The Hemi feels sluggish, and acceleration is noticeably weaker than before.
  4. Whining noise from the fuel tank – A healthy fuel pump is quiet. If you hear a loud whirring or buzzing from the rear of the truck, the pump is struggling.
  5. Intermittent starting issues – The truck starts fine some days and refuses to start on others. This is a classic sign of a failing pump.
  6. Check engine light – The computer may detect low fuel pressure and trigger a diagnostic trouble code.
  7. Engine overheats – A failing fuel pump can cause the engine to run lean, which increases operating temperatures.

If you notice any of these symptoms together, the fuel pump should be your first suspect. But before you order a new one, rule out simpler issues like a clogged fuel filter or a bad fuel pump relay.

Diagnosing the Problem Before You Replace Anything

Before spending money on a new fuel pump, run through these quick checks:

  1. Listen for the pump – Turn the key to the ON position (without cranking the engine). You should hear a brief hum from the fuel tank area. No sound means the pump is not getting power or is dead.
  2. Check the fuel pump fuse and relay – A blown fuse or failed relay will stop the pump completely. These are cheap to replace and easy to check.
  3. Test fuel pressure – Connect a fuel pressure gauge to the test port on the fuel rail. The 5.7L Hemi should show roughly 58 to 64 PSI with the key on and engine running. Low pressure points to a weak pump.
  4. Check for voltage at the pump connector – Use a multimeter to verify the pump is receiving 12 volts when the key is turned on. No voltage means the problem is in the wiring or relay, not the pump.

Once you confirm the pump is the issue, proceed with the replacement.

OEM Part Numbers and What You Need to Know

When shopping for a replacement fuel pump module for your 2009 Dodge Ram 1500 5.7 Hemi, you will come across several OEM part numbers. These are the numbers the dealer uses to order the correct part for your truck:

  1. 68050962AA – The original fuel pump module part number for 2009-2010 Ram 1500 with 5.7L V8.
  2. 68050962AB – A superseded version of the original part.
  3. 68050962AC – The latest factory revision of the module, which replaces the earlier versions.
  4. RL050962AA – A remanufactured version sold through Mopar dealers.

Your 2009 Ram 1500 5.7 Hemi may use any of these depending on the production date. The aftermarket replacements listed with these interchange numbers will fit your truck correctly.

One important note: the fuel pump module for the 5.7L Hemi is the same unit used on the 2009-2010 Ram 1500 with the 3.7L V6. However, it does not fit the 4.7L V8 models, so always verify your engine size before ordering.

Replacement Cost Breakdown

The cost to replace a fuel pump on a 2009 Dodge Ram 1500 varies significantly depending on who does the work and which parts you choose.

Professional installation costs:

  1. Dealer service center – $1,182 to $1,306 including parts and labor. Dealers use factory-recommended parts and have mechanics trained specifically on Dodge trucks.
  2. Independent repair shop – $1,077 to $1,190 including parts and labor. Independent shops often use aftermarket parts that work just as well at a lower price point.
  3. National average across all vehicles – Between $611 and $894, but the Ram 1500 runs higher because the fuel tank must be lowered to access the pump.

DIY replacement costs:

  1. Fuel pump module (aftermarket) – $159 to $330 depending on brand.
  2. Fuel pump module (OEM) – Around $193 for a Delphi unit from online parts retailers.
  3. Seal ring and gasket – Usually included with the module, but you may need to buy separately if not.
  4. Fuel line disconnect tool – $10 to $20 at any auto parts store.
  5. Total DIY cost – Roughly $200 to $400 for the parts, saving you $700 to $900 in labor.

If you are comfortable working on your truck, the DIY route saves a significant amount of money.

Step-by-Step DIY Replacement Guide

Replacing the fuel pump on your 2009 Ram 1500 5.7 Hemi is a moderately difficult job. Plan on spending 2 to 4 hours if it is your first time, and make sure you have the right tools before you start.

Tools you will need:

  • Socket set with metric sizes (10mm, 12mm, 13mm)
  • Wrenches
  • Screwdrivers
  • Floor jack and jack stands
  • Fuel line disconnect tool
  • Safety goggles and gloves
  • Fire extinguisher (keep it nearby)

Step 1: Relieve fuel system pressure

Remove the fuel pump fuse from the fuse box, then crank the engine until it stalls. This burns off the pressure in the fuel lines. Turn the key off and disconnect the negative battery cable.

Step 2: Access the fuel tank

The fuel tank on a 2009 Ram 1500 sits under the rear of the truck. You can either lower the tank from underneath or remove the pickup bed for easier access. Lowering the tank is the more common approach. Raise the truck on jack stands, support the tank with a floor jack, and remove the straps and mounting hardware.

Step 3: Drain the fuel tank

Use a siphon pump to remove as much fuel as possible. This makes the tank lighter and easier to handle. Keep the fuel in an approved gas can for disposal or reuse.

Step 4: Disconnect fuel lines and electrical connectors

Use the fuel line disconnect tool to release the quick-connect fittings. Label the lines so you know which one goes where during reassembly. Unplug the electrical connector from the fuel pump module.

Step 5: Remove the old fuel pump module

Turn the locking ring counterclockwise using a hammer and a brass punch or a large screwdriver. Lift the module straight out of the tank. Be careful not to bend the float arm during removal.

Step 6: Install the new fuel pump module

Transfer the rubber seal (if not included with the new module) to the tank opening. Insert the new module carefully, making sure the float arm has room to move freely. Press down and turn the locking ring clockwise until it seats firmly.

Step 7: Reconnect everything

Reattach the fuel lines and electrical connector. Install the tank back in place, tightening the straps securely. Lower the truck and reconnect the battery.

Step 8: Test the system

Turn the key to the ON position and listen for the pump to prime. Check all connections for leaks. Start the engine and let it idle, then inspect underneath the truck for any fuel leaks before driving.

Choosing the Right Fuel Pump Brand
