The diesel leak off pipe connects the injector to the spill rail, which takes the excess fuel back to the fuel pump and then back to the tank. They are small braided hoses that can wear down over time and draw air into the system. The following article will talk out how to deal with a leaking diesel leak off pipe.



Here are the main points of the article:

  • What cause my diesel leak off pipe to leak?

  • What is important when there is a diesel leak off pipe leak?

  • How do you stop a diesel leak off pipe leak?


1.What cause my diesel leak off pipe to leak?

The biggest cause of failure of common diesel leak off pipes is excessive anti-leakage or backflow. The cause of this condition is internal wear on the part of your pilot valve, nozzle or seal. The defective parts allow the fuel to be returned to the fuel system or diesel tank through the diesel leak off pipe.

2. What is important when there is a diesel leak off pipe leak?

If there is a leak, turn off the car immediately. Remove the fuel pump fuse, wrap the diesel leak off pipe in a lined towel, drain the diesel, and start the car. Keep the car running until it stalls. This step reduces the fuel pressure in the fuel rail and allows for safe removal of the fuel rail.


3. How do you stop a diesel leak off pipe leak?

When diesel leak off pipes leak, they are often replaced unnecessarily. Unless the diesel leak off pipe body has a leak, which is rare, simply replace the O-ring seal. Cleaning the diesel leak off pipe is also a good idea when repairing leaks, and cleaning and servicing the entire diesel leak off pipe is the best way. Diesel leak off pipe are held in place by a common injector guide rail. To remove a diesel leak off pipe, remove the guide rail. This will remove them all. You can follow the following steps to deal with a leaking diesel leak off pipe.

1.When the car is idling, lift the hood to check the diesel leak off pipe guide. A strong smell of fuel is a good sign of a fuel leak. However, look carefully at the top and bottom of the fuel rail. Bear in mind and be careful that the fuel injection system is under high pressure and the gas ejected from the injector seal is highly flammable.

2. Unplug the diesel leak off pipe wires and remove the fuel rail bolts that connect the rail. Remove any associated diesel lines or clamping clamps to prevent the rails from being lifted to remove the fuel injector from the engine. Once loose, lift the rail and take off each diesel leak off pipe. They are held in place by comfortable O-rings and are easily pulled out. There is no need to keep them in order.

3. Remove upper and lower O-ring seals from the diesel leak off pipe. The diesel leak off pipe should then be placed into a carburetor soaking basket and place the basket in the carburetor cleaning bucket. Let the diesel leak off pipe soak for a few hours to completely remove the carbon deposits. After soaking, rinse the syringe with clean water and dry it immediately with compressed air.

4. Install new O-rings. Confirm that they are designed for diesel use and are suitable for vehicles under repair. Standard O-rings can quickly become damaged and ineffective. Lightly coat the diesel leak off pipe with petroleum jelly and insert it into the fuel rail. Reinstall the lower part of the fuel injector into the engine interface and secure the rail bolts back in place. Reattach any clamps or fuel lines. Install the fuel pump fuse and start the engine. Check the fuel injector while the car is running to make sure there are no leaks.
