Yes. In a Windsor engine, the oil goes from the pump directly to the filter. The stock oil pressure sender is after that.

A cheap (Fram), clogged, or too small filter can be restrictive. The pump is pushing against the restriction, and that increases the pressure enough to open the relief valve. Everything after the filter then has a lower pressure, and a lower flow.

I prefer either the Motorcraft FL1-A or a Purolater Pro-1 filters.
