Have you recently replaced the injectors in your diesel truck? Are you looking for a way to help extend the life of your new injectors and protect your investment? At InjectorsDirect.com we know that any downtime for your truck is costly, and want to help provide you with a proactive and cost-effective way to keep your fuel system trouble-free.

We are excited to announce that we have added Stanadyne Performance Formula® Diesel Fuel Additive to our robust product line. Cases available with 8 oz. ($124.99) or 16 oz. ($94.99) bottles  – with FREE Shipping!

In the years since common rail fuel systems were designed and introduced, fuel formulas have changed significantly. The most notable change has been the removal of sulfur which previously acted as a natural lubricant for injectors and pumps. The decreased lubricating properties of ultra-low sulfur diesel fuel have contributed to accelerated wear and component failure in modern diesel fuel injection systems. Stanadyne Performance Formula® helps protect your investment by restoring these lubricating properties which reduces wear and component failure rates significantly.

CP4 High Pressure Fuel Pump Failure

CLICK HERE to purchase our LML CP4 High Pressure Fuel Pump Failure Kit

The 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year range. Failure of this CP4 pump is usually catastrophic, causing instant contamination of the entire fuel system with metal particulates. Chances are, if you’re looking at this page, you’re well aware of the problem. Below we will discuss the reasons for this failure, how to diagnose a pump failure, and show you the parts you need to properly fix your vehicle.

Why Does it Fail?

The short answer: lack of lubricity. Lubricity is most commonly defined as the ability of a fluid to minimize the degree of friction between surfaces in relative motion under load conditions.

The CP4 injection pump creates higher pressures with less volume than its predecessor, the CP3 pump. Although this makes it a more efficient pump, the lack of volume creates a lack of lubrication since these pumps rely on the diesel fuel to act as a lubricant.  In addition to the higher pressure and lower volume, the removal of sulfur from modern diesel fuel (Diesel #2 or Ultra-Low Sulfur Diesel) also destroys compounds that exist in the fuel naturally that would normally contribute to increased lubricity. Some fuel resellers mix lubricity-increasing additives into their fuel prior to sale, but this is not consistent and not well-regulated. Using a commercially available diesel fuel additive can be helpful, but cannot be guaranteed to prevent CP4 pump failure.

Diagnosing a Pump Failure

The LML and LGH CP4 pumps most commonly fail due to this lack of lubrication which causes internal metal parts (the drive cam, cam follower or pump piston, as well as the housing itself) to rub against each other and begin to shave off small metal particles. These particles are immediately distributed throughout the fuel system causing catastrophic failure. Some pumps actually seize up completely and burst the aluminum housing open as a result of this failure.

Using lubricity additives doesn’t guarantee that your pump won’t fail someday, so it’s important to know what steps to take when it happens to you.

If you’re experiencing a hard start or no start, or are getting the following trouble codes; P0087, P0088, P0191, or P128E, a pump failure could be the problem.

Remove the CP4 pump and then the fuel pressure regulator for inspection. If the body casing of the pump is cracked, as in the picture, or you find metallic debris on the fuel pressure regulator screen (pictured right) this is indicative of a pump failure.

Repairing Your Vehicle

GM Mandates that the below steps be performed:

• Replace: Pump, rails, injectors, all high pressure fuel lines, return lines, and fuel filter
• Clean and flush: All fuel chassis lines, filter pipes, and other engine mounted fuel system pipes (low pressure)
• Remove and clean/flush: Fuel tank and fuel sender

InjectorsDirect.com has put together complete repair solution for LML/LGH CP4 Pump failure using all OEM parts (pictured below.) Simply flushing the fuel system is inadequate, and could lead to residual contaminants in your fuel system. Contamination is the number one cause of repeat injector failure, and replacing all of the fuel system components is the only way to prevent recurring contamination issues.

We offer this kit in a few different convenient configurations to meet your needs, by default it includes:

  • Bosch OEM New or Remanufactured LML Injectors (8)
  • BOSCH® OEM New CP4 Pump (Updated housing, camshaft, roller tappets and gear pump)
  • Bosch OEM New Fuel Rails (2)
  • Bosch OEM New Return Line Assembly
  • GM OEM New High Pressure Fuel Lines (Pump to rail, rail to rail & rails to injectors)

Keep Your Fuel System Flowing In the Cold Months

With Winter approaching and temperatures beginning to drop, it’s time to start thinking about how to keep your diesel fuel flowing well through the Winter months. If proper precautions are taken, you can prevent issues that may occur when diesel fuel is left cold and alone.

What Happens to Diesel Fuel in Cold Temperatures?

When anything begins to cool, the molecules start to slow down, eventually freezing. For a quick science refresher, when water reaches 32 degrees Fahrenheit (or 0 degrees Celsius) it freezes and turns to ice. Coincidentally, at around 32º F and below, diesel #2 can begin to crystallize and cloud your tank – this is known as the cloud point and trouble is on the horizon. So when your windshield starts to get frosty, keep in mind your diesel fuel could be next in line.

Pour Point – Fuel Gelling

Diesel fuel contains paraffin, an oily liquid also used as an ingredient to make candles. You can probably see where this is going. When outside temperatures dip 10-20º F below the cloud point, the cooled diesel fuel is going to turn your fuel filter and system into its best impression of a candle. This state is known as the pour point and is widely referred to as fuel gelling. When your diesel fuel begins to gel, it stops flowing freely through your fuel system, and your injectors may not be able to deliver adequate fuel. Your vehicle may not perform well, or in some instances may not run at all.

Be Proactive – Use Additives

Using additives can effectively change the pour points of your diesel fuel, allowing you to brave the cold. If you live in an area that regularly experiences below freezing temperatures, it’s best to start using additives as soon as the temperature begins to drop into range. Adding mixtures, such as ones sold by Stanadyne, can reduce pour points by as much as 40º, giving you the confidence you need to make the haul in the dead of winter.

Use Diesel #1 or “Winter Blend Diesel”

If your fueling station of choice offers diesel #1 during the winter months, this is can be a good temporary alternative, and can also be mixed with existing diesel #2 in your tank to help lower the pour point. Diesel #1 has cloud and pour points in the -40º F range, helping to prevent fuel gelling in the winter. Keep in mind that diesel #1 has reduced lubricating properties and should not be used long-term as it can cause premature wear to your fuel system. Many fuel stations also offer a “winterized blend” of diesel #1 and #2 which can be an option for those cold months. Both of these options should be considered temporary, as both can result in decreased lubricity and reduced fuel economy.

Stay Warm Out There

Whether you use additives or a winter fuel blend in your tank, make sure you pay attention to the weather, so you can spend more time on the road and less time in the garage.

Stay warm out there!
