If you install a filter on the inlet side to the pump make sure it is 100 microns. A typical fuel filter is either 10 or 35 microns (intended for placement after the pump on the pressure side) and they are way too restrictive for the inlet side. The restriction can cause a vacuum to form just after the filter, especially on a hot day. You may then find yourself under the car removing the fuel line to purge the air pocket. Been there.
