2004 Ford Ranger Edge Fuel Pump: Complete Replacement Guide, Symptoms, and Cost Breakdown

The bottom line: If your 2004 Ford Ranger Edge is cranking but won't start, sputtering under load, or showing signs of fuel starvation, the fuel pump is nearly always the culprit. Replacing it is a well-documented job that you can do yourself in a weekend if you have basic mechanical skills. Expect to pay roughly $49 to $310 for the fuel pump assembly itself depending on the brand you choose, plus $225 to $400 in labor if you hire a shop for a total professional replacement cost between $275 and $710 or more . The 2004 Ford Ranger Edge uses an in-tank electric fuel pump, and there are important compatibility details you absolutely need to know before ordering a replacement.

This guide covers everything you need: the symptoms of a failing pump, how to confirm the diagnosis, the exact parts you need, and a step-by-step replacement process that works for the 2004 through 2006 model years. We also break down where your money goes and which replacement brand offers the best balance of price and reliability.

1. How to Recognize a Failing 2004 Ford Ranger Edge Fuel Pump

A bad fuel pump rarely fails without warning. It usually gives you signs that slowly get worse over time. If you catch it early, you can avoid being stranded on the side of the road.

Here are the most common symptoms:

1. Hard starting or extended crank time – The engine cranks longer than usual before firing up. This happens because the pump cannot build adequate fuel pressure quickly enough.
2. Engine sputtering or hesitation during acceleration – You press the gas pedal and the truck stumbles or feels like it is running out of gas even though the tank has fuel.
3. Whining noise from the fuel tank area – An electric fuel pump that is about to fail often makes a loud, high-pitched whine. This means the pump motor is working harder than it should, often due to restricted flow or worn internal components.
4. Engine dies unexpectedly – The vehicle may stall while driving, especially at highway speeds, and then refuse to restart.
5. Poor fuel efficiency – When the pump cannot maintain proper fuel pressure, the engine computer compensates with a richer fuel mixture, which hurts gas mileage.
6. Check Engine Light – A failing fuel pump can trigger codes like P0087 (fuel rail pressure too low) or P0191 (fuel rail pressure sensor range/performance) .

What NOT to do first: Before condemning the fuel pump, check the inertia fuel shutoff switch . On the 2003–2007 Ford Ranger, this safety switch is located in the passenger-side footwell . If it was accidentally triggered (during a rough off-road trip, a minor collision, or even a hard impact), it cuts power to the fuel pump entirely. Resetting it is free and might save you an unnecessary repair .

Another quick check: confirm you are actually losing fuel pressure and not just replacing parts blindly. A fuel pressure gauge attached to the test port on the fuel rail should read 40–60 psi with the key on and the engine running. If the pressure drops immediately after turning the key off, the pump's check valve inside the assembly is likely worn .

2. What Fuel Pump Fits the 2004 Ford Ranger Edge?

The 2004 Ford Ranger Edge was available with either a 2.3L four-cylinder , a 3.0L V6 , or a 4.0L V6 engine, and all of them share the same basic in-tank fuel pump module design for 2004–2006 model years . But here is where you need to be careful: not all Rangers use the same pump, because the wheelbase matters .

Critical fitment notes:

• Fuel pump modules are tied to the vehicle's wheelbase .
• The 2004–2006 Ford Ranger with a 117.4"/117.6" wheelbase uses one specific pump module .
• Rangers with a shorter 111.4"/111.6" wheelbase (regular cab with a short box) or a longer 125.7"/125.9" wheelbase (SuperCab) use a different module .

If you order the wrong one, the pump flange will not line up with the tank opening, and you will waste time and money on a return.

Which OEM part number do you need?

The factory Ford part numbers you will encounter are:

1. 4L5Z-9H307-BB or 4L5Z-9H307-BF – Used for some 2004 models
2. 5L5Z-9H307-BA – Used for 2005 models
3. 6L5Z-9H307-B , 6L5Z-9H307-BA , or 6L5Z-9H307-E – Used for 2006 models

The 6L5Z-9H307-E is the later superseding part number that also fits 2004 and 2005 models in many cases . The 6L5Z-9H307-D is another superseded variant that replaced earlier part numbers like 6L5Z-9H307-A and PFS-316 .

When you shop online, you will also see aftermarket part numbers that cross-reference to these OEM numbers. The most common ones are:

• FG0881 – This is a widely used aftermarket equivalent that fits 2004–2006 Rangers with 2.3L, 3.0L, and 4.0L engines .
• E2357M – Another popular aftermarket cross-reference that fits the same model years and also covers Mazda B2300, B3000, and B4000 twins .
• SP2007M – Listed as an interchange part number for the 2004–2006 range .

A key compatibility fact: A premium option like the Motorcraft PFS-1023 fuel pump module assembly is designed specifically for the Ranger (2004–2007) with a 126" wheelbase . The PFS-1023 is a higher-cost OEM-grade part, and if your Edge has a 126-inch wheelbase (which applies to the SuperCab body style), that is the one you need rather than the 117.4-inch module .

To recap, for a standard cab 2004 Ford Ranger Edge with a 111.6" wheelbase, you need the short-wheelbase module. For an extended cab with a 125.9" wheelbase, you need the long-wheelbase module .

3. Fuel Pump Replacement Cost: What You Can Expect to Pay

The total cost of replacing the fuel pump on your 2004 Ford Ranger Edge depends on two main factors: the price of the parts and the amount of labor. Estimates vary depending on whether you do the job yourself or pay a professional.

Cost by part type:

1. Aftermarket complete fuel pump assembly – $49 to $104 for the full module including the pump, sending unit, and strainer . This is the most budget-friendly option, and quality varies by brand. Some aftermarket options are excellent and come with warranties, while others may fail prematurely.
2. Mid-tier aftermarket (GMB, US Motor Works) – These typically run between $80 and $150 and are known for decent reliability, though some users report issues with included hardware not matching perfectly .
3. OEM Motorcraft or genuine Ford module – Expect to pay $250 to $310 or more for the factory part . For example, the Motorcraft PFS-1023 has a list price of approximately $465 but can be found discounted to around $302 from online Ford parts dealers .
4. Budget aftermarket options on eBay – You can find complete assemblies for $45 to $55 . For instance, one listing shows a fuel pump assembly for $46.54 with shipping, though international shipping costs are high . Another listing has a similar part for $45.99 . These are generally no-name or lesser-known brands, so buyer beware.

Cost by service type:

• DIY replacement cost – $49 to $310 for the part, plus your time. You will also need to buy about $20 to $40 in tools (fuel line disconnect tools and a T-55 Torx bit) if you do not already own them .
• Professional replacement cost with aftermarket parts – $275 to $505 total, including labor .
• Professional replacement cost with OEM parts – $475 to $710 or more , depending on your local labor rates .

Dealerships and independent shops in urban areas typically charge between $75 and $150 per hour for labor . The fuel pump replacement on a Ford Ranger usually takes 2 to 6 hours , and a significant portion of that time is spent accessing the pump .

For comparison, the average national cost for a fuel pump replacement across all vehicles is between $611 and $894 , so the Ranger is actually cheaper than average because the pump is relatively accessible .

4. Step-by-Step: Lifting the Bed vs. Dropping the Tank

On the 2004–2006 Ford Ranger, there are two ways to access the fuel pump on top of the gas tank: lift the pickup bed or drop the fuel tank. The vast majority of DIYers prefer lifting the bed, and for good reason.

Why lifting the bed is the better choice:

1. No need to drain the fuel tank – If your tank is full, dropping it means safely siphoning or pumping out 20+ gallons of gasoline first.
2. No fighting with fuel lines and straps underneath the truck – Everything is accessible from above, which is significantly more comfortable and safer.
3. Faster overall – Most people can do it in 2 to 3 hours total, versus 4 to 6 hours when dropping the tank.

What you need for the bed-lift method:

1. A T-55 Torx bit for the six bed bolts
2. A ratchet and extension
3. Fuel line disconnect tools (plastic or metal, available at any auto parts store)
4. A jack and jack stands for supporting the bed
5. Penetrating oil for rusted bolts

The basic procedure:

1. Disconnect the battery negative terminal . This eliminates any chance of sparking near fuel vapor.
2. Relieve fuel system pressure . Remove the fuel pump relay from the power distribution box under the hood, then crank the engine for a few seconds. It will stall because no fuel is being pumped, and this safely releases pressure in the lines.
3. Remove the six bed bolts . These are Torx-head bolts, one at each corner and two in the middle of the bed. Apply penetrating oil and let it soak for 15 minutes if they are rusted.
4. Disconnect the fuel filler neck . Loosen the clamp and separate the rubber hose from the bed.
5. Disconnect the taillight wiring harness near the rear of the frame so the bed can be lifted freely.
6. Lift the bed with a helper or an engine hoist . Raise it high enough to access the top of the fuel tank. Place jack stands under the bed for safety.
7. Locate the fuel pump module on top of the tank. It is a round plastic flange held down by a large locking ring.
8. Clean the area around the locking ring thoroughly before opening it, so no dirt falls into the tank.
9. Use fuel line disconnect tools to separate the fuel supply line and the return line from the pump module. Push the tool into the fitting and turn it to release the locking tabs.
10. Remove the locking ring with a hammer and a drift punch. Tap it counterclockwise until it turns freely.
11. Carefully lift the fuel pump module out of the tank. It will have the pump, the sending unit float arm, and a rubber gasket. Note how the float arm is oriented so you can install the new one correctly.
12. Transfer the O-ring or gasket to the new pump module. Most aftermarket assemblies include a new O-ring, and some include a new lock ring .
13. Install the new pump by lowering it into the tank in the same orientation. Press it down so the flange seats onto the tank.
14. Reinstall the locking ring and tap it clockwise until it is tight.
15. Reconnect the fuel lines – push them onto the fittings until you feel the clip click into place. Pull gently to make sure they are locked.
16. Lower the bed and install the bolts – Torque the six bed bolts to spec.
17. Reconnect the battery , then turn the key to the "ON" position for about 3 seconds without cranking. You should hear the fuel pump prime (a brief hum from the rear of the truck).
18. Crank the engine and check for leaks . Let it idle for a few minutes and inspect the top of the tank for any fuel weeping around the flange.

If you do not want to lift the bed, dropping the tank is also a valid approach but requires a transmission jack to safely lower the tank, plus you will need to disconnect the filler neck, fuel lines, and the tank's electrical connector. Lifting the bed is more straightforward and requires less specialized equipment beyond a helper .

5. Choosing the Right Replacement Fuel Pump Brand

Not all fuel pumps are equal. When you compare brands, the price difference reflects the quality of the internal motor, the materials used, and how likely the pump is to survive years of daily driving.

Your main options:

1. Budget aftermarket (no-name, eBay specials)
These are tempting because they are cheap. A complete assembly can cost as little as $45 to $55 . However, reliability is a gamble. Some users report that the pump works fine for years, while others describe premature failures, wrong part numbers shipped, and poor fitment. If you choose this route, make sure the seller has a positive feedback rating above 98% and offers a return policy.

2. Value-tier aftermarket (AutoBest, PHILTOP)
Brands like PHILTOP offer a fuel pump assembly (model FG0881 ) that fits the 2004–2006 Ranger for about $55 to $65 . These typically include a 3-year warranty and come with all necessary hardware such as the strainer and O-ring . AutoBest is another brand known for good value for budget-conscious repairs, with straightforward installation and reliable function for the price .

3. Standard-tier aftermarket (GMB, US Motor Works, Delphi)
These are established brands. GMB is a respected Japanese manufacturer that makes reliable mid-tier pumps. US Motor Works gets positive feedback for performance and uses corrosion-resistant materials in its sensors. Some users have reported receiving incorrect strainers or missing small parts, so it pays to check the box contents before you take everything apart .

4. Premium OEM (Motorcraft, genuine Ford)
The Ford 6L5Z-9H307-E or Motorcraft PFS-1023 is the gold standard. These are built to the exact factory spec, come with a 12-month/12,000-mile warranty, and are guaranteed to fit . The downside is the price – $250 to $310 or more – but many owners say it is worth it to do the job only once and never worry again .

5. High-performance alternative (KEMSO)
For owners who want a reliable fuel pump that exceeds OEM performance standards without paying a premium price, KEMSO is a standout choice. Unlike generic no-name pumps, KEMSO fuel pumps are designed to meet or exceed original equipment specifications, using high-quality components that offer better durability. See further details in the section below.

6. Cost-Saving Tips Before You Start

Replacing the fuel pump is a chance to address a few other maintenance items at the same time, because the tank is open and you already have everything apart.

Do these things while you are in there:

1. Replace the fuel filter . A clogged old fuel filter will strain your brand-new pump and can cause premature pump failure. This is a cheap part, typically $15 to $30 , and it is highly recommended to replace it at the same time .
2. Inspect the fuel lines for any signs of dry rot, cracks, or leaks while the connections are accessible.
3. Clean the top of the tank thoroughly before opening it so no dirt falls inside. Even a small amount of debris can clog the new pump's strainer.
4. Check the rubber filler neck hose and its clamps, since you had to disconnect it to lift the bed. Replace the clamps if they are rusted.

A valuable habit for future longevity: Do not run your fuel tank down to empty. Gasoline in the tank acts as a coolant for the electric fuel pump motor. Frequently running the tank below a quarter full can cause the pump to overheat, dramatically shortening its lifespan. Keeping at least a quarter tank is one of the simplest ways to extend the life of any in-tank fuel pump .

7. Step-by-Step Cost Breakdown at a Glance

Here is a simple table to help you understand where your money goes when replacing the 2004 Ford Ranger Edge fuel pump.

If you do the work yourself, your total out-of-pocket cost will be roughly $49 to $150 for a reliable aftermarket assembly, or $250 to $350 if you choose OEM parts. That is a significant saving compared to paying a shop .

8. DIY vs. Professional Installation: What Works Best?

The 2004 Ford Ranger Edge has a fairly accessible fuel pump, making it one of the more DIY-friendly mid-size trucks. The bed-lift method is well documented, and a mechanically inclined person can typically finish the job in about 3 to 4 hours.

DIY is a good choice if you:

1. Already own basic tools like a ratchet set, torque wrench, and jack stands
2. Are comfortable working around fuel systems and follow proper safety precautions (disconnecting the battery, relieving fuel pressure, and working in a well-ventilated area)
3. Have a helper to lift the bed, since a Ranger bed is heavy, especially if it is wet or has bed liners installed
4. Want to save $200 to $400 in labor costs

Calling a professional makes sense if you:

1. Do not have a safe place to lift and support the bed
2. Are not comfortable with any part of the fuel system work
3. Have a full fuel tank and prefer not to deal with draining it
4. Do not want to risk damaging the bed bolts – these are known to rust and can shear off if they are too corroded and you try to remove them without proper technique

If you choose a shop, always get a written estimate that itemizes both parts and labor. Ask about the shop's hourly rate and whether they will use aftermarket or OEM parts, so you know what to expect .
