2015 Dodge Durango Fuel Pump Replacement: A Complete DIY Guide

If your 2015 Dodge Durango is having trouble starting, stalling during acceleration, or making a whining noise from the rear of the vehicle, the fuel pump is likely failing. Replacing the fuel pump on a 2015 Dodge Durango is a challenging but doable DIY job that can save you between $650 and $950 compared to a shop repair. The fuel pump is located inside the gas tank, which means you’ll need to drop the tank to access it. This guide walks you through the entire process, from diagnosing the problem to installing the new pump and testing the system.

Symptoms of a Failing Fuel Pump on a 2015 Dodge Durango

Before you start replacing parts, make sure the fuel pump is actually the problem. The most common signs of a failing fuel pump in a 2015 Dodge Durango include:

  • Engine sputtering or hesitation during acceleration, especially when going uphill or carrying a load
  • Long cranking time before the engine starts, particularly when the engine is hot
  • Stalling at idle or sudden loss of power while driving
  • Whining noise coming from the fuel tank area, which is often the first warning sign
  • Check Engine Light with codes like P0087 (low fuel pressure) or P0230 (fuel pump circuit malfunction)

If you experience any of these symptoms, test the fuel pressure at the Schrader valve using a gauge. For a 2015 Durango, the fuel pressure should be around 50–60 PSI at idle. If the pressure is lower than spec, the pump is likely failing.

What You’ll Need for the Job

Replacing the fuel pump on a 2015 Dodge Durango requires some specialized tools. Here’s what you’ll need:

  • New fuel pump module – Make sure it’s compatible with your engine size (3.6L V6 or 5.7L Hemi)
  • Fuel pump lock ring tool – A specialty tool for removing the retaining ring on top of the tank
  • Brass punch and hammer – As an alternative to the lock ring tool, brass reduces spark risk
  • Fuel line disconnect tool – For separating the fuel lines from the pump module
  • Floor jack and jack stands – To safely support the vehicle and fuel tank
  • Siphon kit – To drain the fuel tank before removal
  • Shop towels and drain pan – For cleaning and catching spilled fuel
  • 10mm, 15mm sockets – For battery and tank strap bolts
  • Safety glasses and gloves – Gasoline is hazardous to skin and eyes

Step-by-Step Fuel Pump Replacement Process

Step 1: Safety First

Disconnect the negative battery cable using a 10mm socket. This prevents any electrical sparks or accidental engine starts while you work. Park the Durango on a level surface and engage the parking brake. Have a fire extinguisher nearby, just in case.

Step 2: Relieve Fuel System Pressure

The fuel system is under high pressure (50–60 PSI), so you need to relieve it before disconnecting anything. Remove the fuel pump relay from the underhood fuse box, then start the engine and let it idle until it runs out of gas and stalls. Turn the ignition off and replace the relay. This step is critical for safety.

Step 3: Drain the Fuel Tank

If the tank is full or nearly full, drain as much fuel as possible using a siphon kit. Gasoline weighs about 8 pounds per gallon, so a full tank is extremely heavy and dangerous to handle. Store the drained fuel in approved gas cans.

Step 4: Raise and Support the Vehicle

Raise the rear of the Durango using a floor jack and securely support it with jack stands. Never rely on the jack alone to hold the vehicle up. Make sure the vehicle is stable before getting underneath.

Step 5: Disconnect Fuel Lines and Electrical Connectors

Locate the fuel tank underneath the vehicle, near the rear axle. Use a fuel line disconnect tool to carefully separate the fuel lines from the pump module. Be prepared for some fuel spillage, so have a drain pan ready. Disconnect the electrical connector from the pump module and the filler/vent hoses using hose clamp pliers.

Step 6: Remove the Fuel Tank

Place a floor jack under the fuel tank to support its weight. Remove the tank straps using a 15mm socket. Lower the tank slowly and carefully, making sure the lines and hoses are fully disconnected. Once the tank is on the ground, move it to a clean, well-ventilated work area.

Step 7: Clean the Pump Area

Before opening the tank, wipe dirt away from the top of the module and the lock ring using shop towels. Dirt in the tank can ruin the new pump. This simple step can save you from having to do the job twice.

Step 8: Remove the Lock Ring and Fuel Pump Module

Use a fuel pump lock ring tool to turn the lock ring counterclockwise and remove it. If you don’t have the tool, you can use a brass punch and small hammer carefully on the ring tabs. Brass reduces the risk of sparks. Lift the module straight up and angle it as needed to clear the float arm (fuel level arm). Remove the old seal/O-ring from the tank opening.

Step 9: Install the New Seal and Module

Install the new fuel pump module tank seal/O-ring into the tank groove. Make sure it lays flat and isn’t twisted. Carefully lower the new module into the tank, watching the float arm so it doesn’t bend. Install the lock ring and tighten it using the fuel pump lock ring tool. Torque the lock ring to 55 Nm (41 ft-lbs).

Step 10: Reinstall the Fuel Tank

Place the tank on the floor jack and raise it partway. Reconnect the electrical connector and fuel lines, pushing until you feel and hear a solid click. Reconnect the filler and vent hoses using hose clamp pliers, and make sure the clamps are fully seated. Raise the tank fully and reinstall the straps using a 15mm socket. Torque the tank strap bolts to 68 Nm (50 ft-lbs).

Step 11: Reconnect Battery and Prime the System

Reconnect the negative battery cable using a 10mm socket. Turn the key to the ON position (engine OFF) for 3 seconds, then OFF for 10 seconds. Repeat this cycle 3 times to prime the system. Start the engine and let it run.

After Repair Checks

After the repair is complete, inspect the vehicle for leaks. With the engine running, look under the vehicle at the fuel line connections and tank seal area. Shut the engine off and re-check for any fuel smell or wet spots. Take the Durango for a 10–15 minute test drive, then re-check for leaks again. If the fuel gauge reads incorrectly, re-check the module seating and connector engagement.

DIY vs. Shop Cost

Replacing the fuel pump on a 2015 Dodge Durango at a shop costs between $900 and $1,600 for parts and labor. If you do it yourself, the cost drops to $250 to $650 for parts only. That’s a savings of $650 to $950. Shop labor rates typically run $100 to $150 per hour, and this repair takes a shop approximately 3 to 5 hours. By doing it yourself, you keep that money in your pocket.

Common Mistakes to Avoid

  • Using a generic pump that doesn’t match your vehicle’s specifications. Fuel pumps vary in flow rate, pressure, and electrical connectors. Always buy a pump specifically designed for your make, model, and engine size.
  • Forgetting to clean the tank before installing the new pump. Dirt and debris can ruin the new pump in a matter of minutes.
  • Damaging the float arm during removal or installation. This will cause the fuel gauge to read incorrectly.
  • Overtightening the lock ring. This can distort the seal and cause leaks. Use a torque wrench to hit the spec of 55 Nm.

Final Thoughts
