2017 Dodge Durango Fuel Pump: Replacement Guide and Symptoms

If you own a 2017 Dodge Durango and suspect the fuel pump is failing, you need to act fast. The most common symptoms include engine sputtering, long cranking times, stalling at idle, and a whining noise from the fuel tank area . Replacing the fuel pump on a 2017 Durango is a job that typically takes a shop 3 to 5 hours and costs between $900 and $1,600 for parts and labor. If you do it yourself, you can save $650 to $950, with DIY costs ranging from $250 to $650 for just the parts . However, this is a serious repair involving gasoline, so safety and proper procedure are critical.

Symptoms of a Failing Fuel Pump

Before you start replacing anything, you need to confirm the fuel pump is actually the problem. Here are the most common signs that your 2017 Dodge Durango fuel pump is failing:

  • Engine sputtering or hesitation: Loss of power during acceleration or when driving uphill is a classic sign. The engine may feel like it's "starving" for fuel .
  • Long cranking time: If the engine takes 5 seconds or more to start, especially when the engine is hot, the fuel pump may not be building pressure quickly enough .
  • Stalling at idle: The engine may suddenly shut down when you're stopped at a light or in traffic due to inconsistent fuel flow .
  • Whining noise from the fuel tank: A loud humming or whining sound coming from the rear of the vehicle, near the fuel tank, is a clear indicator the pump is wearing out .
  • Check Engine Light: You may see codes like P0087 (Low Fuel Pressure) or P0230 (Fuel Pump Circuit Malfunction) .

A simple fuel pressure test can confirm the diagnosis. The fuel pressure on a 2017 Durango should be between 50 and 60 PSI at idle . If it's lower than that, the pump is likely bad.

Tools and Parts You Will Need

For a 2017 Dodge Durango, the fuel pump is located inside the fuel tank. You will need to either drop the fuel tank or access it through an access panel under the rear seat. Most Durango models require dropping the tank. Here is a list of what you will need:

  • New fuel pump assembly: Make sure it's the correct part for your engine size (3.6L V6 or 5.7L Hemi) .
  • Fuel line disconnect tool set: 3/8 inch and 5/16 inch sizes are common .
  • Fuel pump lock ring tool: A specialty tool for removing the retaining ring on the fuel pump module .
  • Floor jack and jack stands: To safely raise and support the vehicle, and to lower the fuel tank .
  • Drain pan and shop towels: For catching fuel spills .
  • Socket set: 10mm, 15mm, and other common sizes .
  • Brass punch and hammer: If you don't have the lock ring tool, a brass punch is safer than steel because it reduces the risk of sparks .
  • Penetrating oil: To loosen rusted bolts or fittings .
  • Safety gear: Gloves, safety glasses, and a fire extinguisher .

Step-by-Step Replacement Guide

Step 1: Safety First

Park the vehicle on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery cable using a 10mm socket. This prevents any electrical sparks or short circuits . Have a fire extinguisher nearby and work in a well-ventilated area away from open flames or sparks .

Step 2: Relieve Fuel System Pressure

Before you disconnect any fuel lines, you must relieve the pressure in the fuel system. Locate the fuel pump relay in the underhood fuse box and pull it out. Then start the engine and let it idle until it runs out of fuel and stalls. This releases the pressure. Replace the fuel pump relay after the engine dies .

Step 3: Drain the Fuel Tank

If the fuel tank is full or nearly full, it will be very heavy and dangerous to handle. Use a siphon pump to drain as much fuel as possible into approved gas cans. This also makes the tank easier to lower and maneuver .

Step 4: Access the Fuel Tank

Raise the rear of the Durango using a jack and securely support it with jack stands. The fuel tank is located underneath the vehicle, near the rear axle . You will need to remove the bolts that hold the fuel tank straps in place. Use a 15mm socket to remove these bolts .

Step 5: Lower the Fuel Tank

Place a floor jack under the fuel tank to support its weight. Carefully lower the tank just enough to access the fuel lines and electrical connectors on top of the tank. Do not drop the tank all the way yet. You need to disconnect the lines first .

Step 6: Disconnect Fuel Lines and Electrical Connector

Use the fuel line disconnect tool to release the fuel lines. Slide the disconnect tool into the fitting to release the internal spring clip, then pull the lines apart . Be prepared for some fuel spillage, so have a drain pan and shop towels ready. Disconnect the electrical connector by pressing the release tab and pulling it apart .

Step 7: Remove the Fuel Tank

Once all lines and hoses are disconnected, slowly lower the fuel tank fully using the floor jack. Slide the tank out from under the vehicle .

Step 8: Clean the Pump Area

Before opening the tank, wipe away any dirt and debris from the top of the fuel pump module and the lock ring. Dirt that falls into the tank can ruin the new pump immediately .

Step 9: Remove the Lock Ring and Old Fuel Pump Module

Use the 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 a small hammer to carefully tap the ring tabs counterclockwise. Brass is preferred because it reduces the risk of sparks . Once the ring is removed, carefully lift the old fuel pump module straight up out of the tank. You may need to angle it to clear the float arm (the fuel level sending unit). Be careful not to bend the float arm .

Step 10: Install the New Fuel Pump Module

Remove the old O-ring or seal from the tank opening. Install the new O-ring that came with your new fuel pump module. Make sure it lays flat in the groove and is not twisted . Carefully lower the new fuel pump module into the tank, again watching the float arm to avoid bending it. Align the module properly — the fitting on top of the pump should face toward the driver's side . Install the lock ring and tighten it using the lock ring tool. Torque the lock ring to 55 Nm (41 ft-lbs) .

Step 11: Reinstall the Fuel Tank

Place the fuel tank back on the floor jack and raise it partway. Reconnect the electrical connector and fuel lines. Push the fuel lines until you feel and hear a solid click, indicating they are locked in place . Reconnect the filler hose and vent hose. Raise the tank fully and reinstall the straps. Torque the tank strap bolts to 68 Nm (50 ft-lbs) .

Step 12: Reconnect Battery and Prime the System

Reconnect the negative battery cable. Turn the key to the "ON" position (engine off) for 3 seconds, then turn it off for 10 seconds. Repeat this cycle 3 times to prime the fuel system and build pressure .

Step 13: Test and Check for Leaks

Start the engine and let it idle. Inspect under the vehicle for any fuel leaks at the fuel line connections and the tank seal area. Shut the engine off and check for any fuel smell or wet spots. Take the vehicle for a 10 to 15 minute test drive, then re-check for leaks again . If the fuel gauge reads incorrectly, re-check the module seating and connector engagement .

Common Mistakes to Avoid

  • Forgetting to relieve fuel pressure: Opening pressurized fuel lines can spray gasoline in your face and create a fire hazard .
  • Getting dirt in the tank: Even a small amount of debris can clog the new pump's strainer and cause premature failure. Always clean the area before opening the tank .
  • Overtightening the retaining ring: This can warp the sealing surface or crack the plastic module. Use a torque wrench and follow the spec .
  • Skipping the fuel filter replacement: A clogged old filter will stress your new pump and reduce its lifespan. Replace the filter at the same time .
  • Not testing before full reassembly: Always prime the system and check for leaks before putting everything back together .
