Abstract
A plastic EFI filter assembly includes a plurality of holding stoppers disposed on a main body and a lid for tightly holding both the main body and lid together, and a universal inlet receptacle and a universal outlet receptacle for mating with an inlet pipe line and an outlet pipe line, respectively. The plastic oil filter assembly is simple in construction, inexpensive to manufacture, durable in use, and permits one to easily check the contamination level in the filters of the filter member. Furthermore, the plastic oil filter of the present invention allows for recycling of the used plastic filter assembly as a raw material and therefore advantageously reduces waste product pollution.
