02 Dakota Fuel Pump: How to Replace and What to Buy

If you own a 2002 Dodge Dakota and are experiencing engine stalling, hard starting, or a failing fuel gauge, the problem is most likely the fuel pump. Replacing the fuel pump on a 2002 Dakota is a straightforward but labor-intensive job that requires dropping the fuel tank or removing the truck bed. The key to a successful repair is buying the correct fuel pump module for your specific engine and tank size, and ensuring precise alignment during installation. For the best reliability, consider a high-performance OEM replacement like the KEMSO Fuel Pump, which offers a lifetime warranty.

What Fuel Pump Fits a 2002 Dodge Dakota?

The 2002 Dodge Dakota came with several engine options, and the fuel pump module you need depends on your engine and whether you have a 22-gallon or 24-gallon tank. Most aftermarket fuel pump assemblies cover the 2.5L L4, 3.9L V6, 4.7L V8, and 5.9L V8 engines . The common replacement part numbers include E7116M, E7117M, and P74738M .

  • 2.5L and 3.9L engines: Often use the E7116M or E7117M module .
  • 4.7L and 5.9L engines: Also use the E7116M, but some models with a 24-gallon crew cab tank require a different module .
  • Crew Cab with 24-gallon tank: For 2000-2003 Dakota crew cabs with a 24-gallon tank, you need a specific fuel pump module that fits the larger tank. These are often listed as 5014884AF or 150125-A .

The fuel pump module assembly includes the pump, sending unit, float, and strainer, making it a complete drop-in replacement . Some modules, like the ECCPP brand, do not include the pressure sensor, so you must reuse the original black sensor from the old assembly .

Signs Your 2002 Dakota Fuel Pump Is Failing

Before you start the replacement, confirm the pump is the problem. Common symptoms include:

  1. Engine stalls or dies while driving: The pump cannot maintain consistent fuel pressure .
  2. Hard starting or no start: The engine cranks but does not fire because fuel is not reaching the injectors .
  3. Reduced power under load: A weak pump restricts fuel flow, causing the engine to lose power on hills or when accelerating .
  4. Fuel gauge malfunctions: A faulty sending unit in the pump module gives inaccurate fuel level readings .
  5. Whining noise from the fuel tank: A failing pump often makes a loud humming or buzzing sound .

How to Replace the Fuel Pump on a 2002 Dodge Dakota

Replacing the fuel pump on a 2002 Dakota involves removing the fuel tank or the truck bed. Most mechanics recommend removing the bed for easier access, but dropping the tank is also common . Here are the critical steps:

Step 1: Relieve Fuel Pressure
Pull the fuel pump relay from the fuse box and run the engine until it stalls. This removes pressure from the fuel lines . Disconnect the negative battery cable for safety.

Step 2: Drain the Fuel Tank
Use a siphon or pump to drain as much fuel as possible. This reduces weight and prevents spills .

Step 3: Access the Fuel Pump
You have two options:

  • Remove the truck bed: Unbolt the bed and lift it off with help .
  • Drop the fuel tank: Disconnect the filler neck, vent lines, and fuel lines. Lower the tank using a jack .

Step 4: Remove the Old Pump Module
Use a fuel pump lock ring tool to remove the retaining ring. Lift out the old module carefully. Note the orientation of the alignment marks on the tank and module .

Step 5: Install the New Pump Module
This is the most important step. Align the fuel pump module correctly to avoid binding the float arm against the tank wall. Dodge Dakotas (especially 1991-1996 models) have narrow tanks, and improper alignment causes inaccurate fuel gauge readings . The pump module has an alignment arrow; match it to the mark on the tank . If the mark is not visible, align the pump so the fuel line outlet points toward the front of the vehicle .

Step 6: Reassemble
Install the new O-ring, lock ring, and reconnect all fuel lines and wiring. Raise the tank or bed back into place. Reconnect the battery and fuel pump relay.

Step 7: Test the System
Turn the key to the "on" position (without starting) to prime the fuel system. Check for leaks. Start the engine and verify the fuel gauge works correctly.

Important Tips for a Successful Replacement

  • Replace the fuel filter: On 1993 and older Dakotas, the fuel filter is on the frame rail. On 2002 models, the filter is often integrated into the pump module. Confirm your setup .
  • Clean the tank: If the tank is dirty or rusty, have it professionally cleaned before installing the new pump .
  • Use a new O-ring and lock ring: Always replace the sealing ring and lock ring to prevent leaks .
  • Check the fuel pump alignment after tightening: Verify the pump module is still in the correct position after securing the lock ring .
  • Listen for the pump: When you turn the key to "on," you should hear the pump run for a few seconds. If not, check the electrical connections .
