En el pasado, el PL420 se usaba como el primer filtro primario para las vigas del tanque de combustible. No hay presión. El riel común está presurizado y el PL420 está bajo presión negativa.


Antes de la aparición de la bomba de presión electrónica, la copa transparente es muy segura, no hay daños por presión a la copa transparente, pero con la llegada de la bomba de presión electrónica, los dos filtros gruesos del motor cambian de presión negativa a 4 presiones positivas o Incluso mayor presión. La antigua taza transparente PL420 tiene el riesgo de fugas de aceite.


Algunos OEM cambiaron el PL420 en el motor al PL421 sin una taza. Sin embargo, algunos fabricantes de equipos originales no consideraron este problema. Todavía cargaron la PL420. (Ahora hay Delong) hay riesgos de diseño.


Se recomienda usar el filtro PL421 para los modelos equipados con una bomba electrónica.
