Filter PL420 can't replace filters PL421
2019-06-21

In the past, the PL420 was used as the first primary filter for the fuel tank girders. There is no pressure. The common rail is pressurized, and the PL420 is under negative pressure.


Before the appearance of the electronic pressure pump, the transparent cup is very safe, there is no pressure damage to the transparent cup, but with the advent of the electronic pressure pump, the engine's two coarse filters change from negative pressure to 4 positive pressures or even greater pressure. The old-fashioned PL420 transparent cup has the risk of oil leakage.


Some OEMs changed the PL420 on the engine to the PL421 without a cup. However, some OEMs did not consider this problem. They still loaded the PL420. (There are now Delong) there are design risks.


It is recommended to use the filter PL421 for models equipped with an electronic pump.
