Why does a clogging happen in the diesel leak off pipe?


1. How do you diagnose a clogged diesel leak off pipe?

Diagnosing bad or blocked diesel leak off pipes is difficult because it acts like a bad coil, bad spark plug, spark plug wire or electrical problems.

l Start the engine cold and let it idle for 5-10 seconds.

l If possible, use your bare hands to quickly open each diesel leak off pipe and find the one that isn't hot. If the engine is hot, don't do this. If the engine is hot, then drop off the fuel return hose or wet your hand, then quickly touch the leak off pipe.

l Remove the connector from the diesel leak off pipe on the unheated cylinder.

l Check the terminal of fuel diesel leak off pipe joint for corrosion.

l Use an ohmmeter to check if the diesel leak off pipe is powered. Use an ohmmeter to make sure the diesel leak off pipe has the right resistance.

l Reconnect the diesel leak off pipe.

l If you don't have an ohmmeter, you can use a stethoscope or a rubber hose to listen for the tap of the syringe. Place the stethoscope or hose on the diesel leak off pipe and at the other end listen for the injector to click to remove the spark plug lead or disconnect the coil pack or remove the coil pack connected to the cylinder. Start the engine. It should sound the same.

l Remove the spark plug. If the spark plug is dry, the diesel leak off pipe will not send fuel to the cylinder. If the spark plug is wet and smells like gasoline, the injector on the cylinder is not problem.

2. What are the symptoms of a clogged diesel leak off pipe?

The following are the common symptoms of a clogged diesel leak off pipe.

l The engine runs very coarsely

l One, more or all of the cylinders not firing.

l This engine produces no power.

l The engine doesn't want to start.

l Bad emissions

l Bad fuel consumption


3. Why does a clogging happen in the diesel leak off pipe?

Diesel leak off pipes become clogged with hydrocarbons, sediment, and other elements in the fuel. Most fuels contain ethanol. Ethanol is hygroscopic, so it is hygroscopic from the air into the fuel. Water in fuel can cause internal parts to rust. When the fuel filter is damaged, rust can enter the injector. Some smaller and older gas stations have debris and sediment in their storage tanks, which eventually makes its way into the diesel leak off pipe and then are pumped into the tank. The diesel leak off pipe also gets stuck with varnish and gunk, which is formed when fuel is left in the tank for a long time.
