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

14,001 to 16,000 lbs 

16,001 to 19,500 lbs 

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. GP Sorensen® 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
  • 20+ MD Diesel Fuel Injection Pumps
  • 20+ MD Diesel High Pressure Oil Pumps
  • 15+ MD Diesel Turbochargers

Exclusive — New Diesel Fuel Injectors

Diesel Injector

Extensive engineering and manufacturing expertise coupled with high-precision equipment means GP Sorensen® NEW Fuel Injectors include the latest engineering enhancements to match the OE injector. GP Sorensen® NEW Fuel Injectors are built for the highest levels of precision and consistency, which delivers uncompromising quality, durability, and fuel economy.

What sets our new diesel injectors apart:

  • New OE-production fuel injector provides superior quality, emissions compliance, and fuel economy

  • Precision-manufactured with the latest engineering enhancements to match the OE injector

  • Product of OE-production design, development, engineering, and manufacturing processes, including sub-micron machining and complex assembly systems, to ensure durability

  • Undergoes extensive dynamometer, hot gas test stand, and diesel emissions testing for proper performance

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

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.

Upgraded Diesel EGR Cooler Kit

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 Diesel EGR Cooler Kit with an upgraded 20 spiral tube design. 


Diesel Fuel Injection Control Modules (FICM)

We’re proud to offer a line of Diesel Fuel Injection Control Modules (FICM) with 100% new, upgraded power supply boards. Featuring a re-engineering layout, our FICM power supply distributes heat more evenly, keeping diodes and other critical components cooler and preventing the failure that can occur in competitors’ units.

Diesel Fuel Transfer Pump

As a high-quality replacement part, our 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 GP Sorensen® 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 GP Sorensen® engineered enhancements to ensure proper sealing and improved performance.

How GP Sorensen's 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:

"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.

Diesel Glow Plugs

Diesel engines use compression to induce combustion, unlike gasoline engines, which use spark plugs. When diesel engines are cold, however, compression is enhanced by the introduction of a pre-heater, known as a glow plug. Once activated, the glow plug, which has coiled wiring in its tip, flares up and emits an intense electrical heat that warms the combustion chamber and assists compression during a cold-start. It can also be used for post heating, which can improve fuel and emission performance.

With GP Sorensen's Diesel Glow Plug installed, startup time will be reduced. Plus, when the engine does start, there will be less smoke and reduced emissions. That’s because our glow plug has an improved tip design.

High-grade, corrosion-resistant material prolongs longevity during engine peak performance

Dual-coil design draws less current, which reduces power consumption and extends battery life

Improved cone design reduces detonation and post-heating time

Heating coil located closer to tube for faster response

Horizontal Fuel Conditioning Module (HFCM)

The Horizontal Fuel Conditioning Module (HFCM) is a part of the complex Ford 6.0L Power Stroke Engine. Like all diesel engines, it requires quality fuel. To help provide that quality, the HFCM filters out 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 creating the 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.
