In the LML Duramax, the CP4.2 pressurizes diesel fuel as high as 29,000 to 30,000 psi. This extreme high pressure facilitates fine atomization within the engine’s cylinders. With future, tighter particulate matter emission standards in mind, Bosch designed the CP4 line to produce (and handle) as much as 39,000 psi.

What are high pressure gas lines?
The highest capacity pipelines - high-pressure transmission gas pipelines - transport gas over long distances at very high pressure, linking sources of gas supply with local gas distribution networks or major points of consumption. We want to ensure the safety of anyone living or working near our natural gas pipelines.
What size is a fuel line?
What size is 6an fuel line? Similarly one may ask, what size are fuel lines? Most stock applications came with 5/16-inch fuel line, but for many street vehicles and mild race applications 3/8-inch (AN 6) fuel line is a good upgrade. High performance applications and racers using alcohol will use 1/2-inch (AN 8) fuel line.
How do you Prime a diesel engine?
How do you prime a Caterpillar diesel engine? Prime the fuel system by turning the ignition on (Run position) for 30 seconds, but do not start the engine. This allows the pump to prime the system. Turn the ignition off, and then crank it for 15 seconds. If it does not start, repeat the first task and this one until it starts (cycle the key).
How do you clean a diesel fuel injector?
- Get a diesel fuel additive that is compatible with your truck or car.
- Turn off the engine and ensure your gas is below ¼.
- Locate and open the truck fuel tank
- Pour recommended amount of fuel additive into the gas tank.
- Add more gas to the gas tank and run the engine for 10-15 minutes.
What is high pressure diesel fuel line?
Fuel injection lines are required to deliver the fuel from the high pressure pump to the combustion engine without any loss of pressure, without any hindrance to the flow and without impairing the functions of the fuel injection components.
How much pressure is in a diesel fuel line?
Both GDI and CRD systems use a high-pressure pump, but the pressures are very different—3000 psi for GDI and up to 28,000 psi for a CRD system.
Can you use rubber hose for high pressure fuel line?
Standard rubber vacuum or heater hose should never be used in fuel applications. The hose will deteriorate from the inside out and can plug fuel filters and carburetors with rubber debris, long before it springs an external leak.
Are fuel lines high pressure?
Line Dancing In fuel-injected systems, fuel feed line pressures can be as high as 120 psi so it's best to make sure that the lines and connections in your system are up to task. High-pressure rubber fuel injection lines are readily available, but they can also be replaced with steel-braided lines for added strength.
Is there a special fuel line for diesel?
The American Boat & Yacht Council (ABYC) recommends the Type B1 fuel hose for diesel-based applications. The Type A1 hose is the best option for gasoline supply. This hose is less permeable, highly durable, heat resistant and does not collapse under high pressure or vacuum.
What happens if fuel pressure is too high?
If fuel pressure is too high, your vehicle's engine could be over fueled, leading to many of the symptoms listed below. Some of these symptoms include your engine running rough, poor fuel economy and black smoke from the exhaust.
Is vinyl tubing OK for diesel fuel?
Use only fuel rated hose for everything between the tank and the IP. Tygon hose is fine for return lines, and you could even get away with vinyl hose for the returns just temporarily for testing purposes.
Can you use silicone hose for diesel?
One of the things we find gets asked often is can your silicone hoses for used for fuel? The simple answer is no, standard silicone hoses are porous and therefore not suitable for oil or fuel.
What is the best material for fuel lines?
The best fuel line material depends on your needs. However, the best material for fuel lines is polytetrafluoroethylene or PTFE. PTFE fuel line is made of plastic material specifically known as Teflon. This fuel line material is impervious is resistant to the degenerative fuel effects which could form vapor barriers.
Is there a difference between diesel and gas fuel line?
Diesel fuel is thicker than gasoline, and as such provides more power and mileage per gallon. Gasoline engines, on the other hand, are lighter and deliver higher performance than diesel engines. There aren't diesel engines in sports cars for much the same reasons there aren't gasoline engines in big trucks.
Can you reuse high pressure fuel lines?
NOTE: The high pressure fuel injector line seal is a single-use item and cannot be reused.
Can hydraulic hose be used for diesel fuel?
Hose for fuel service is of different composition, to prevent deterioration resulting in softening, or hardening\cracking, etc. While Diesel fuel is a light oil, the additives in it would deteriorate the hydraulic-service rubber hose. Please include your vehicle details in your signature line.
Low-Pressure Petroleum Hose
Made of tough Buna-N rubber, this hose has the durability to stand up to gasoline, fuel oil, and other petroleum-based products.
Flexible Low-Pressure Petroleum Hose
With a tighter bend radius than other petroleum hose, this hose can easily twist and turn around equipment.
UL-Listed Low-Pressure Gasoline Hose
Commonly used to transfer gasoline, this hose is also known as curb pump hose.
Ultra-Chemical-Resistant Soft Plastic Tubing
An FEP liner gives this tubing better chemical resistance than any of our other soft tubing. It also provides a smooth interior for unrestricted flow.
High-Temperature Soft Rubber Tubing for Chemicals
Use this resilient tubing in high-temperature chemical applications up to 400° F.
Hard Plastic Tubing for Chemicals
Hard walls give this tubing excellent strength in high-pressure and vacuum applications.
Crack-Resistant Hard Plastic Tubing for Chemicals
You don’t have to worry about this tubing cracking due to stress or impact— even over a wide range of temperatures.
Raw Material Management
Setting Up The Build
- Once a part has been quoted, and a purchase order has been received, the job can begin. At that point, the first step is to enter the XYZ bend data into our secure project Bend Pro software system. Keep in mind, our bend machinery can perform multiple radius bends on one line (although we could have a friendly debate about whether that’s best practice from an engine…
Our Fabrication Process
- First, we cut the raw tubing to length. Next we deburr, chamfer, and prep the tube ends. The tubes then get sleeves. Then we end-form the tubes. End-forms can take many shapes, depending on the application. These include: After the tube has been properly end-formed, we bend the part per print. At this point in the process, they look like parts. However, the job isn”t done yet.
Pack and Ship
- Diesel parts move from clean to our dedicated shipping area. Once in shipping, we package, label, and ship parts according to spec. When requested, we can ship using an OEM’s packaging or labels, either to a warehouse or direct to an end-user. DTI also interfaces with logistics. We schedule freight pick-ups with carriers, deliver parts ourselves when feasible, and frequently go …
