Mason explains tharat the footage shown in the  was taken from an engine where the high pressure fuel pump had locked up, causing the engine to fail. He clarifies that under normal circumstances, the cab or engine would not need to be removed to replace the fuel system.

He goes on to say that if you own a 6.7 liter power stroke, you have likely either experienced this problem or heard about it from others. Mason then proceeds to provide viewers with all the information he knows about the problem, including how to fix it correctly and prevent it from happening in the future.

 

Overall, Mason’s article provides valuable information for 6.7 liter power stroke owners who are dealing with high pressure fuel system problems. By sharing his knowledge and experience, he helps viewers save money and avoid future issues with their engines.

The 6.7 liter power stroke CP4 high pressure pump is known to fail, and one of the biggest driving factors behind this failure is poor maintenance and dirty or contaminated fuel. Going 50,000 miles on a set of fuel filters is way too long, and many people do not change their filters until they have gone 50 to 60,000 miles. This is insane and can lead to a lot of problems.

 

The lower filter housing is called a conditioning module, and it is a water separator. It is there to separate water that naturally builds up in diesel fuel and to filter the diesel fuel before it goes into the engine. However, after 40 to 50,000 miles, the fuel filters are completely clogged up and cannot filter the fuel properly.

Contaminated fuel is another factor that can cause the high pressure pump to fail. Diesel fuel can become contaminated with water, dirt, and other debris, which can cause damage to the fuel system. It is important to use high-quality fuel and to keep the fuel tank clean to prevent contamination.

 

In conclusion, poor maintenance and dirty or contaminated fuel are the main reasons why the 6.7 liter power stroke CP4 high pressure pump fails. It is important to change the fuel filters regularly and to use high-quality fuel to prevent damage to the fuel system.

Diesel fuel is naturally dirty and contaminated, which is why diesel trucks require multiple filters to ensure that the fuel is properly filtered before it reaches the engine. The high pressure system in diesel trucks requires clean fuel to function properly, and any contamination or junk in the fuel can cause serious damage to the engine. 

 

Clogged filters can also significantly reduce the volume of fuel that is able to travel to the high pressure pump, which can cause a decrease in performance and efficiency. Fuel volume is just as important as pressure in diesel engines, and a lack of volume can cause serious issues. 

Bosch CP4 and other mechanical fuel pumps on diesel trucks use diesel fuel as a lubricant for the moving parts inside the pump. Diesel fuel is oily and lubricates well, making it an ideal choice for this purpose. 

 

In conclusion, diesel fuel is naturally dirty and requires proper filtration to ensure that it does not cause damage to the engine. Clogged filters can significantly reduce fuel volume and cause performance issues, and diesel fuel is used as a lubricant in mechanical fuel pumps.

 

In this article, the speaker discusses the importance of proper fuel filtration in diesel engines. They explain that diesel fuel is used to lubricate the engine and if the fuel filter is clogged, the engine will not be properly lubricated and will not work. The speaker emphasizes that contaminants in the fuel can cause serious problems, including diesel exhaust fluid, gas, water, and rust.

 

The speaker explains that diesel exhaust fluid is a common contaminant that can cause expensive damage if not properly handled. They caution against confusing the blue and green caps on the fluid containers, as this can lead to costly mistakes. Gasoline is another common contaminant that can cause serious damage to diesel engines. The speaker notes that people accidentally pump gas into diesel engines every day.

Water is another contaminant that can cause problems in diesel engines. While a small amount of water is expected in diesel fuel, excessive amounts can cause problems with the conditioning module and lead to rust in the engine. Rust is a major problem in diesel engines, as it can clog the tiny spaces that fuel needs to pass through.

 

The speaker concludes by cautioning against pouring diesel exhaust fluid on the ground, as this can cause environmental damage. Proper handling and filtration of diesel fuel is essential for the proper functioning of diesel engines.

In this article, the speaker discusses the dangers of putting gasoline in a diesel fuel system. Gasoline can crystallize and turn hard inside the fuel system, causing damage to the pump, injectors, and lines. This is because gasoline does not lubricate the system like diesel fuel does. 

 

If gasoline has been added to a diesel fuel system, it may be possible to drain the fuel out, but it depends on how long the gasoline was in the system and how much made it to the pump and injectors. Gasoline is lighter than diesel, so it may settle on top of the fuel in the tank and not make it to the pump. 

 

To diagnose this problem, the speaker suggests taking the vehicle to a local Ford dealer and paying for a diagnosis. However, for those who want to diagnose the problem themselves, there are multiple ways to do it. 

 

Overall, it is important to never put gasoline in a diesel fuel system to avoid costly damage to the fuel system.

 When it comes to finding metal in a diesel engine, there are a few methods that can be used. However, one preferred method is to pull the upper and lower intake. This method allows for the most metal to be found. 

 

To begin, the upper intake is pulled, which is a pitch and a half. Then, the lower intake is pulled, which is much easier once the upper one is out of the way. This process can take anywhere from two to three hours for someone who is doing it for the first time. However, for someone who has done it multiple times, it usually only takes about 20 to 30 minutes to pull both intakes. 

 

Once the intakes are pulled, the pump can be seen sitting in the valley towards the front of the engine. It times off the cam gear in the front of the engine, not the back where the turbo is located. On top of the pump is the high-pressure fuel pressure control valve. This valve can be removed by using two torx bit T25s. It is important to be careful when removing the valve as it has a little o-ring on it that can break if not handled properly. 

 

When the valve is removed, it may have what is called “fairy dust” on it. This is little tiny particles of metal that can indicate a problem with the fuel system. If there is anything in the fuel system such as dirt, rust, or metal, a fuel system will need to be installed. 

There are a few other ways to diagnose a problem with the fuel system. One way is to pull the lower fuel filter housing and check for metal. However, usually only the ones that really come apart will put metal that far back in the system. Another way is to check the fuel volume control valve on the back of the driver’s side fuel rail. 

 

In conclusion, pulling the upper and lower intake is a preferred method for finding metal in a diesel engine. It allows for the most metal to be found and can help diagnose problems with the fuel system. If there is anything in the fuel system such as dirt, rust, or metal, a fuel system will need to be installed.

 

When it comes to diagnosing fuel system issues in a vehicle, there are a few things to keep in mind. One of the first things to consider is how to access the fuel system to check for any metal debris. This may require pulling out the fender well or breaking open the fuel system in some way.

 

One way to diagnose fuel system issues is to pull the fuel pressure control valve out of the top of the pump. This is where you are likely to find the most information about what is going on with the system.

If you do find that you need to repair the fuel system, it is important to do it correctly the first time. This means avoiding taking it to a mechanic who may not have the expertise to handle the job. Instead, it is recommended to take it to a Ford dealer who can program the iqa codes for the injectors and ensure that the repair is done properly.

 

If you do decide to tackle the repair yourself, you will need to purchase a high pressure fuel kit or a fuel contamination kit. The latter option will come with everything you need to repair the high pressure system, but it may be more expensive than buying individual parts.

 

Overall, diagnosing and repairing fuel system issues can be a complex process, but with the right tools and expertise, it can be done effectively.

 

When it comes to repairing a fuel system, there are certain things that need to be replaced in order to ensure that the system runs smoothly. One of the most important components of a fuel system is the fuel pump, which is responsible for delivering fuel to the engine. However, simply replacing the fuel pump is not enough to ensure that the system is working properly.

In addition to replacing the fuel pump, it is also necessary to replace the injectors and lines. This is because these components can become contaminated over time, which can lead to problems with the fuel system. When replacing these components, it is important to make sure that all of the fuel and contamination is removed from the system.

 

To do this, it is necessary to drop the fuel tank and drain all of the fuel out of it. If a computer is available that can command the pump on, it is possible to push the fuel out through the lines. However, most people do not have access to this type of equipment, so dropping the tank is usually necessary.

 

Once the tank has been dropped, it is important to clean the inside of the tank and blow out the lines. This will help to ensure that all of the contamination is removed from the system. It is also important to make sure that there is no metal left in the system, as this can cause problems with the new components.

 

While it may be tempting to try to save money by only replacing the fuel pump, this is not a good idea. If the injectors and lines are not replaced, the new pump will quickly become contaminated and fail. In fact, it is possible for the system to fail within minutes of replacing the pump if the other components are not replaced as well.

In conclusion, when repairing a fuel system, it is important to replace all of the necessary components. This includes the fuel pump, injectors, and lines. It is also important to make sure that all of the fuel and contamination is removed from the system. By following these steps, it is possible to ensure that the fuel system will run smoothly and last for a long time.

 

Have you ever wondered why it costs so much money to fix a diesel truck? In today’s times, rebuilding a truck for ten thousand dollars may seem reasonable, but the reality is that it costs much more than that. There are two main reasons why diesel truck repairs are so expensive.

 

The first reason is the cost of the fuel system kit. This kit alone can cost up to six thousand dollars, and some of the newer ones can cost up to seven thousand dollars. This is an insanely expensive part of the repair process, and it is one of the main reasons why diesel truck repairs are so costly.

 

The second reason why diesel truck repairs are so expensive is that they are very labor-intensive. It can take two to three days to complete a repair, even for experienced mechanics. Some may think that they can complete the repair in four hours, but this is not possible without sacrificing the quality of the repair. It is a very complex process that requires a lot of attention to detail, and it is not recommended for anyone to attempt this repair unless they are very experienced with working on diesel engines or have worked on similar projects in the past.

It is important to note that mechanics do not work for free. While they may love fixing your piles of junk, they are there to get paid for their services. So, the next time you need to get your diesel truck repaired, keep in mind that the cost is not just for the parts but also for the labor-intensive process that goes into fixing it.

 

In this article, the speaker talks about the cost of repairing a fuel system in a vehicle and how it can be quite expensive. The reason for this is that everyone involved in the repair process, including the mechanic and the dealer, is looking to make a profit. As a result, the labor costs can drive up the overall price of the repair, which can range from $8,000 to $10,000 depending on the labor rate.

 

The speaker also suggests that if you accidentally pour something into your fuel system, it’s a good idea to check with your insurance company to see if they will cover the cost of the repair. This can save you a lot of money, as the repair can be quite expensive.

 

When it comes to saving money on this type of repair, the speaker admits that there isn’t much advice he can give. While you could try to diagnose the problem yourself, the repair process will still require the same amount of labor, so you won’t save much money there. However, he does recommend shopping around and getting quotes from multiple dealers to see if you can find a better price.

Finally, the speaker talks about how to prevent this problem from happening in the first place. He suggests using high-quality fuel and avoiding filling up at gas stations that have dirty pumps. He also recommends changing your fuel filter regularly and using a fuel system cleaner to keep your system running smoothly. By taking these steps, you can help prevent costly repairs down the line.

 

Maintaining your vehicle’s fuel system is crucial to avoid costly repairs down the road. One of the most important things you can do is to change your fuel filters regularly. This simple step can prevent your fuel system from tearing apart.

 

However, many people neglect to maintain their vehicles, which leads to expensive repairs. If you want to avoid these costly repairs, you need to get ahead of the problem by changing your fuel filters and oil early on.

 

One common question people ask is about the CP4 pump disaster prevention kit. This kit is designed to prevent the CP4 pump from failing, which is a common problem in diesel engines. However, the effectiveness of this kit is debatable.

According to the speaker in the article, he doesn’t believe that the disaster prevention kit works. He doesn’t see how the bypass return can save the pump from failing. Even if he had the problem, he wouldn’t trust just replacing the pump without replacing the injectors and everything else.

 

In conclusion, maintaining your vehicle’s fuel system is crucial to avoid costly repairs down the road. Changing your fuel filters regularly is one of the most important things you can do. While the CP4 pump disaster prevention kit may seem like a good idea, it’s effectiveness is debatable.

 

 

 

In this article, the speaker discusses the potential risks of using a disaster prevention kit on a fuel pump. They explain that if the pump were to come apart, it could send metal through the lines and into the injectors, regardless of what preventative measures are in place. As a result, the speaker does not recommend using such a kit and suggests investing in fuel filters instead.

 

The speaker emphasizes the importance of proper maintenance for a fuel system, including changing fuel filters regularly and avoiding putting substances like DEF, gas, or water into the system. By taking care of maintenance, the speaker believes that a fuel system can last for hundreds of thousands of miles, outlasting even the turbo and engine.

 

The speaker also notes that they have upgraded their gear for better audio and article quality in future articles. They express gratitude for their viewers and apologize for the delay in posting new content.
