The pump outlet filter element can only be used in the oil return line filter. The filter element should be maintained and cleaned every once in a while to ensure the normal use of the filter. When cleaning, please be sure to clean it according to the instructions to avoid material corrosion. Chemical fiber filter elements and paper filter elements cannot be used for filtering chemical substances.
 
  Reason for the blockage of the pump outlet filter filter:
 
  1. The circuit is not smooth. This is easy to check. Use a multimeter or a test light to connect it to the plug. Turn on the motor to indicate that there is electricity, and if it does not turn on, it indicates that the circuit is faulty.
 
  2. Circuit failure First check the oil pump relay and oil pump fuse. When the motor is activated, the oil pump relay should be pulled in and there should be voltage output. If there is no voltage output, consider the oil pump relay or the computer-to-oil pump line, or even the driving computer.
 
  3. If there is electricity, it will be much simpler. Remove the oil pump outlet pipe and start the motor. Check for blockage of oil pipes if there is any oil coming out, and disassemble and inspect the gasoline pump if no oil comes out.
 
  4. If the gasoline pump is not blocked by foreign matter, it can be replaced directly!
 
  The solution to the blockage of the pump outlet filter filter is as follows:
 
  This phenomenon belongs to impurities produced by the oxidation of different brands of engine oil additives.
 
  1. If you do not filter in front of the oil pump filter, it will be easy to go up to the filter. The filter has a bypass valve. When the press filter oil pump filter is blocked, the oil does not pass through the oil pump filter and directly enters the main oil passage from the bypass valve without passing through the press filter. Causing blockage of the oil passage. It's more troublesome to handle that way than this.. If it is not easy to clean, it will become more blocked. Besides, impurities can easily damage the oil pump.
 
  2. This is caused by the fact that the oil is not frequently changed on time. If you want to eliminate this situation, there is no other way but to remove the oil pan and then clean the press filter oil filter. It is recommended to wash the interior of the engine with diesel oil and try to remove impurities as much as possible. Flush it, then replace it with new oil, and change the oil on time in the future. Replace the stamped filter on time.
