The Evolving Diesel Engine

Diesel engines have come a long way since the mid-90s. The key to diesel’s evolution has been the advancement of new clean diesel technologies. Today’s advanced renewable diesel fuels have built on the diesel engine’s and emission control system’s near-zero emissions across all applications. Plus, these fuels enhance diesel performance, maintain efficiency over other energy sources, and ensure long-term suitability for sustainability goals.

Superior Medium-Duty Coverage

medium duty trucks

CLASS 4
14,001 to 16,000 lbs 

CLASS 5
16,001 to 19,500 lbs 

CLASS 6
19,501 to 26,000 lbs 

Genuine Diesel Parts for Vehicle Classes 4, 5, and 6

Medium-duty vehicles belong to vehicle classes 4, 5, and 6. These three classes consist of any vehicle with a Gross Vehicle Weight Rating (GVWR) between 14,001 and 26,000 pounds, which is the total combined weight of the truck, including all passengers, fuel, fluids, and payload. These vehicles include everything from parcel delivery trucks to bucket trucks and school buses. NAPA® Echlin® is proud to provide an extensive offering of premium replacement parts for these medium-duty applications, including:

More Than 265 Diesel Engine Management SKUs for Medium-Duty Trucks, including:

  • 70+ MD Diesel Fuel Injectors

  • Manufactured in U.S.A. at TS16949-certified facility


Upgraded Diesel EGR Cooler Kit

6.0L oil cooler


EGR coolers use engine coolant to reduce exhaust gas temperatures before the gas is recirculated through the intake system. Reducing exhaust gas temperatures is critical for reducing NOx emissions. Plus, engines that run with higher EGR temperature don’t adequately cool the combustion, which can reduce the life expectancy of the EGR valve, engine valves, and head gaskets.

But not all EGR coolers are the same. The original equipment EGR cooler’s fin-and-tube-style design is prone to clogging and leaking. Additionally, many aftermarket EGR coolers feature various tube designs that do not provide the necessary cooling. Providing a superior alternative to the OE and competition's designs, we're proud to offer our ECK1 Diesel EGR Cooler Kit with an upgraded 20 spiral tube design.

Diesel Fuel Transfer Pump

As a high-quality replacement part, NAPA Echlin's 100% new Diesel Fuel Transfer Pump is designed to keep constant fuel flow from the vehicle fuel tank to the injection pump. The constant flow allows peak performance to remain consistent during vehicle operation.

Precision-manufactured internal components maintain optimal fuel pressure during vehicle operation 

High-grade composite plastic connector resists cracking when exposed to extreme weather 

Comes complete with jumper harness, fuel line banjo bolt seals, and mounting nuts and washers 


Diesel Fuel Injection Pumps

All NAPA® Echlin® Diesel Fuel Injection Pumps are the product of an exhaustive remanufacturing process designed to ensure maximum quality and durability. 


High Pressure Oil Pumps

Each High Pressure Oil Pump features NAPA® Echlin® engineered enhancements to ensure proper sealing and improved performance.


How NAPA® Echlin® Engineering Helps Eliminate Common 6.0L Failures

During our revamped remanufacturing process, our engineers manually examine hundreds of component parts for consistency in critical wear points to make sure the right components get replaced every time. On top of that, they've also engineered improvements to common 6.0L failures, such as housing leaks:

The Backstory

Original 6.0L high pressure oil pumps
are designed with 
a check ball.

The Problem

Due to a flawed OE design, the check ball
can easily become displaced, leading to
housing leaks and part failure.

Our Solution

We replace the check ball housings
with a new casting that has a threaded
plug to 
ensure proper sealing and
eliminate the original problem.


"Blue Spring" Fuel Pressure Regulator Upgrade Kit

Our "Blue Spring" Fuel Pressure Regulator Upgrade Kit for 6.0L Ford Trucks includes everything needed to rebuild the fuel filter housing, including O-rings, hardware, and a blue spring that increases fuel pressure by 10-15 psi to eliminate potential for injector damage.


Quality-Remanufactured Diesel Injectors

To ensure that our remanufactured diesel injectors perform flawlessly, we first make sure that they remain contamination-free during the rebuild process. We replace every necessary component with new and administer a precise, repeatable process that is followed every time.

Horizontal Fuel Conditioning Module (HFCM)

The Horizontal Fuel Conditioning Module (HFCM) is a part of the complex Ford 6.0L Power StrokeEngine. Like all diesel engines, it requires quality fuel. To help provide that quality, the HFCM filtersout water and other contaminants before the fuel is delivered to the injectors. Other HFCM functionsinclude heating fuel, separating water from fuel, sensing when water is present in fuel, and creatingthe fuel pressure needed to supply fuel to the engine mounted fuel filter.

Our Horizontal Fuel Conditioning Module is a direct OE replacement that comes with a replaceablefuel filter element that can be serviced separately, making it a truly installer-friendly part.

PMD Relocation Kits

On Stanadyne DS4 electronic fuel injection pumps used on all 1994-2002 6.5L GM trucks and vans, the OE pump-mounted driver (PMD) module is mounted directly to the fuel injection pump. This location creates two problems. The first is inefficiency. If a PMD module attached to a fuel injection pump needs to be serviced or replaced, you need to reach the fuel injection pump, which is an extremely timeconsuming,labor-intensive repair. The second problem is that the location on the fuel injection pump subjects the PMD to excessive heat, a known cause of this high failure part.

Our PMD Relocation Kits provide a solution to both problems. If you install the kit upfront when installing the fuel injection pump, you’ll save significant time when diagnosing and replacing the PMD module in the future. As for the heat-related failure, our remote-mount PMD Kit allows you to relocate the PMD, which will help improve service life because of increased airflow around the module, thereby keeping it cooler.
