Where Is the Fuel Filter on a 2024 Ram 2500?

If you drive a 2024 Ram 2500 with the legendary 6.7L Cummins diesel engine, you already know it’s built for power, durability, and heavy-duty work. But keeping it running strong means staying on top of routine maintenance—especially when it comes to the fuel filter.

Knowing where the fuel filter is located is essential for timely replacement, DIY servicing, or simply communicating with your mechanic. In this article, we’ll walk you through the fuel filter location, how the system works, and why using OEM Mopar filters is critical to your truck’s longevity.

Why the Fuel Filter Matters on a Diesel Truck

Unlike gas engines, diesel engines are extremely sensitive to fuel contamination. Even the smallest amount of dirt, rust, or water can cause damage to the high-pressure fuel system—especially the injectors. That’s why the 6.7 Cummins fuel filter is one of the most important parts in your 2024 Dodge Ram 2500 maintenance routine.

Your fuel filter’s job is to remove:

• Dirt and debris
  
  

• Water
  
  

• Rust and corrosion particles
  
  

Without it, you risk injector failure, poor fuel economy, and even engine stalling. And because diesel fuel tends to hold more impurities than gasoline, regular fuel filtration is even more critical.

Where Is the Fuel Filter on the 2024 Ram 2500?

The 2024 Ram 2500 with the 6.7L Cummins features two fuel filters as part of its dual-filter system:

1. Primary Fuel Filter – Under the Driver’s Side Frame Rail

• Location: Underneath the truck, along the driver’s side frame rail
  
  

• Function: Separates large contaminants and water from the fuel
  
  

• Access: You’ll need to raise the truck or use ramps to access this filter safely
  
  

This is the main line of defense, working to catch the larger particles before the fuel reaches the high-pressure pump.

2. Secondary Fuel Filter – On Top of the Engine

• Location: Mounted on top of the engine, near the intake manifold
  
  

• Function: Provides fine filtration before fuel enters the injectors
  
  

• Access: Requires removal of the engine cover for visibility and service
  
  

This filter polishes the fuel by removing finer particles the primary filter missed. Combined, both filters are essential for protecting your common rail injection system.

How Often Should You Replace the Fuel Filters?

Mopar recommends replacing both fuel filters every 15,000 to 30,000 miles, depending on driving conditions. For trucks used in dusty or off-road environments—or for heavy towing—it’s wise to stay closer to the 15,000-mile mark.

Failing to replace fuel filters on time can lead to:

• Reduced performance
  
  

• Hard starting
  
  

• Fuel system damage
  
  

• Warning lights on the dashboard
  
  

Always follow your owner’s manual and use OEM Cummins diesel engine parts or Mopar fuel filters for the best results.

Tools and Parts You’ll Need for Replacement

If you're planning a DIY fuel filter replacement, here’s what you’ll need:

• Mopar fuel filter kit (primary and secondary)
  
  

• 28mm or 1 1/8" socket (for the underbody filter cap)
  
  

• Basic socket set (for engine bay filter)
  
  

• Diesel-safe catch pan
  
  

• New O-rings and seals (usually included with the OEM filter kit)
  
  

• Torque wrench (for proper tightening)
  
  

• Clean diesel fuel (to prime if necessary)
  
  

Using Mopar filters ensures a perfect fit and optimal performance. Generic aftermarket filters may not meet OEM filtration standards or fit securely in the housing.

Benefits of Using OEM Mopar Fuel Filters

• Factory-tested quality
  
  

• Exact fitment for 6.7 Cummins fuel systems
  
  

• High water-separation efficiency
  
  

• Better longevity and reliability
  
  

• Preserves fuel injector life
  
  

OEM filters, like the Mopar fuel filter for 6.7 Cummins, are designed to withstand the pressures and demands of your Ram’s high-performance diesel system.

Final Thoughts

Knowing where the fuel filter is located on your 2024 Ram 2500 empowers you to stay proactive with maintenance. With the primary filter beneath the frame rail and the secondary filter on top of the engine, both play a crucial role in protecting your diesel fuel system.

Stick to a regular fuel filter replacement schedule, and always choose OEM Mopar filters to ensure your Ram runs clean, efficient, and powerful for years to come.

Frequently Asked Questions (FAQs)

1. Do I need to replace both fuel filters at the same time?

Yes. The primary and secondary filters work together. Replacing both ensures consistent fuel filtration and avoids uneven wear on the system.

2. What happens if I use a non-OEM fuel filter?

Non-OEM filters may not fit properly or filter diesel fuel as effectively. This can lead to premature injector failure or voided warranty coverage.

3. How do I know if my fuel filter is clogged?

Symptoms include hard starts, rough idling, reduced fuel economy, or warning lights such as “Water in Fuel” or “Service Fuel Filter.”

4. Can I change the fuel filters myself?

Yes, with the right tools and care. Always relieve fuel system pressure and follow safety procedures. OEM filter kits often include helpful instructions.

5. Is the fuel filter the same for all Ram 2500 trims?

Most 2024 Ram 2500 trims with the 6.7L Cummins use the same dual-filter system, but it’s best to verify with your VIN or check your owner’s manual.
