The original pump includes an inlet strainer, but I don’t think the O’Reilly’s E16078 has one. In principle it’s the same style as the Bosch 0580 254 044 that replaced the factory unit. If you want to add a pre-filter, you can install two 5/16" filters in parallel to avoid fuel starvation and prevent cavitation in the pump. Their only purpose is to protect the pump, the filter up front will protect the injectors.
